A retrospective look at Sirius B in its red supergiant phase
A “what if” retrospective look at Sirius B in its red supergiant
phase, and the first illusive dim light of Sirius C that can’t be too far off. Could the Sirius ABC collective ever go supernovae? http://en.wikipedia.org/wiki/Supernova According to Wikipedia, the extremely nearby and still very massive Sirius star system doesn’t hardly exist as any past, present or future threat, even though having only recently existed, as well as having flashed over to a white dwarf, and Sirius C not having been optically identified. I bet you think we’ve seen just about everything Sirius has to offer. (think again) http://www.cosmicastronomy.com/oscillat.htm#sirius Not that far better instruments haven’t existed that could easily accomplish a thousand fold better and of multiple narrow bandpass imaging results of Sirius, but what the hell when at least an honest amateur gives us a no-charge freebie whack at Sirius, we might as well pay some attention because we got nothing to lose but our self- rightists pride in all things faith-based and/or government moderated. Red giant stars are supposedly many, and yet they remain a little hard to come by, as only a few public images of whatever is within 1000 light years seem to exist that fit within the bloated size and color saturated eye-candy profiles that we’ve been taught to accept, and stellar flashovers are simply next to impossible to record. However, the visible spectrum is extremely limited as to what is otherwise technically accessible from just above and below our genetically limited and thus inferior visual spectrum. (seems entirely odd that our human evolution was rather careless in having discarded so much nifty visual capability, in that other creatures that supposedly lack the necessary intelligence seem to have a far wider visual spectrum capability that includes some UV and IR without any need of applied technology) In most exoplanet and brown dwarf hunting cases, the given primary star has to be looked at multiple hundred times in order to measure any primary or secondary star variations in those photons of any given bandpass filtered application. http://irfu.cea.fr/Sap/en/Phocea/Vie...tu&id_ast=2483 Since Sirius A remains as such a substantial illuminating star is why it’s rather difficult to image much of anything else, especially compromised from within our atmosphere. In this case they were primarily hunting for a potential red dwarf on a 20002500 year elongated/elliptical orbit, instead of seeking to uncover any nearby brown dwarf such as Sirius C .06M. They did however manage to detect a substantial disk of unusual IR intensity surrounding the nearly invisible Sirius B. For Sirius C hunting we need a 100X TRACE instrument with extended dynamic range that can directly image the extremely hot surfaces of Sirius A and B without losing the surrounding details of whatever relatively dim brown dwarf(s). Perhaps a few LHC do-overs can also help us understand what makes subatomic particles, atoms and stars tick, by way of creating artificial black holes, H2/He flashovers and possibly even a terrestrial nova will give us those cosmic laws of physics that’ll some day allow us to make antimatter and fusion kinds of energy and interstellar treks within a given generation, and otherwise improve the quality of terrestrial life (a first for astrophysics) for the rest of us. “Red Giant Star Found to Have Massive Tail” The obvious bow-wave proves that even 64 km/s is pushing towards the intergalactic terminal velocity of such stellar motion for items of this volumetric inflated red giant size (Mira being as little as a mere eight of what the original Sirius B red supergiant should have represented) http://www.efluxmedia.com/news_Red_G...l_077 84.html Mira_A of 1.2 M solar mass and bloated out to several hundred solar radii (UV colorized as bluish): “A dying star situated 400 light years away from us exhibits an unusual and massive tail of heated gas that spreads for more than 13 light years.” Trekking it’s way through space at a seemingly rogue velocity of 64 km/s none the less. http://en.wikipedia.org/wiki/Mira http://www.nasa.gov/mission_pages/galex/20070815/a.html Sirius B could have been looking much like an image of Mira A, except moving along at less than 10 km/s with respect to us, and otherwise nearly 8 fold more massive and certainly having expanded a whole lot larger (1000 solar radii), as viewed in visible and near IR, as that of a nearby red supergiant star, and perhaps nearly half the mass of the star Betelgeuse. http://xmm.esac.esa.int/external/xmm...aab_v2_col.pdf Mira A, plus lots more composite observationology from FAS http://www.fas.org/irp/imint/docs/rst/Sect20/A6.html There are many possibilities as for how Sirius B used to function as a truly massive (9 solar mass) plus that of an extremely vibrant star, thereby ultra hot and unavoidably fast consuming upon itself prior to becoming the impressive red supergiant, as well as creating another planetary nebula or dense molecular phase before ending as the little white dwarf that we can barely see without technology. For all we know, for quite a while Sirius B was a variable kind of red supergiant and then perhaps a slow nova flashover phase prior to finishing off as the compressed white dwarf. These following examples are probably similar or perhaps representing a slightly smaller version of what the Sirius star/solar system looked like once Sirius B had started turning itself from an impressive red supergiant and suddenly into a white dwarf of perhaps 1/8th its previous mass, taking roughly 32~96,000 years for this accellerated mass shedding phase to happen. A few tens of billions of years later is when such a white dwarf eventually becomes a black carbon dwarf, as kind of a black diamond spent star that our universe may or may not be quite old enough to display such examples. http://en.wikipedia.org/wiki/Planetary_nebula http://en.wikipedia.org/wiki/Helix_Nebula http://en.wikipedia.org/wiki/Cat%27s_Eye_Nebula http://apod.nasa.gov/apod/ap031207.html http://www.uv.es/jrtorres/index6.html Betelgeuse has been a massive red supergiant at 20+ fold the mass of our sun, and likely worth somewhat better than two fold the mass of the original Sirius B. Betelgeuse currently having expanded to 1000 solar radii and growing, it'll certainly become a truly impressive flashover whenever it runs out of helium and suddenly transforms itself into a white dwarf that’s nearly the size of Saturn. The soon to be renewed and greatly improved Hubble instrument should accomplish the improved spectrum coverage, along with improved resolution and several extra DB in dynamic range of imaging most everything, along with other existing and soon to be ESA deployed telescopes that are far superior yet, should give us even better composite examples of what Sirius B used to look like, and quite possibly our first light of Sirius C. This kind of public investment in astronomy should give some of us a better deductive kind of observationology, of somewhat less subjective interpretations as to what sort of stellar birth, growth and demise transpired right next door to us, as well as having unavoidably contributed to some of what our solar system has to offer. However, perhaps there’s too much information already known about the Sirius star/solar system for the public to grasp, without causing more faith- based and political harm than good. http://www.cosmicastronomy.com/oscillat.htm#sirius ~ BG |

A retrospective look at Sirius B in its red supergiant phase
Sadly the Sirius star/solar system is perhaps too nearby and still way
too vibrant for our astronomy that's focused on whatever is billions of light years further away. The 100x TRACE-II or TRACEx100 instrument that I've mentioned would cost perhaps at most 1% of the all-inclusive Hubble investment, and that's because of it's relatively compact size, plus that it wouldn't ever need the sorts of risky and spendy human servicing, nor even all that spendy of initial R&D or deployment. This 100x TRACE could also be used to study our own sun and a few others, like the red supergiant Betelgeuse and most anything else that's within its optical resolution and wide spectrum range. ~ BG On May 9, 2:01*pm, BradGuth wrote: A “what if” retrospective look at Sirius B in its red supergiant phase, and the first illusive dim light of Sirius C that can’t be too far off.

A pair of new and improved TRACEx100s might run us $120M, or roughly 1% of our Hubble investment, and that’s without ever having to risk one human cell or strand of DNA, nor causing 1% the global pollution. I might go so far as to suggest situating one of the TRACEx100s at Earth L1, and the other at Earth L2, as that way we could have a stereo view of Sirius, plus many other stereo/3D applications. Either TRACEx100 could also perform multiple OCO duties, as well as some limited Selene/moon related science. ~ BG |

A retrospective look at Sirius B in its red supergiant phase
The cosmic creation of the nearby Sirius star/solar system, as recent
as 200 million years ago, seams a little too good to be true and otherwise a little too damn lucky for us.

Perhaps a few LHC do-overs can also help us understand what makes subatomic particles, atoms and stars tick, by way of creating artificial black holes, H2/He flashovers and possibly even a terrestrial nova will give us those cosmic laws of physics that’ll some day allow us to make antimatter and fusion kinds of energy and interstellar treks within a given generation, and otherwise improve the quality of terrestrial life (a first for astrophysics) for the rest of us. “Red Giant Star Found to Have Massive Tail” *The obvious bow-wave proves that even 64 km/s is pushing towards the intergalactic terminal velocity of such stellar motion for items of this volumetric inflated red giant size (Mira being as little as a mere eight of what the original Sirius B red supergiant should have represented)http://www.efluxmedia.com/news_Red_G...Have_Massive_T... *Mira_A of 1.2 M solar mass and bloated out to several hundred solar radii (UV colorized as bluish): “A dying star situated 400 light years away from us exhibits an unusual and massive tail of heated gas that spreads for more than 13 light years.” *Trekking it’s way through space at a seemingly rogue velocity of 64 km/s none the less. *http://en.wikipedia.org/wiki/Mira *http://www.nasa.gov/mission_pages/galex/20070815/a.html Sirius B could have been looking much like an image of Mira A, except moving along at less than 10 km/s with respect to us, and otherwise nearly 8 fold more massive and certainly having expanded a whole lot larger (1000 solar radii), as viewed in visible and near IR, as that of a nearby red supergiant star, and perhaps nearly half the mass of the star Betelgeuse. *http://xmm.esac.esa.int/external/xmm...osium/173770_m.... Mira A, plus lots more composite observationology from FAS *http://www.fas.org/irp/imint/docs/rst/Sect20/A6.html There are many possibilities as for how Sirius B used to function as a truly massive (9 solar mass) plus that of an extremely vibrant star, thereby ultra hot and unavoidably fast consuming upon itself prior to becoming the impressive red supergiant, as well as creating another planetary nebula or dense molecular phase before ending as the little white dwarf *that we can barely see without technology. *For all we know, for quite a while Sirius B was a variable kind of red supergiant and then perhaps a slow nova flashover phase prior to finishing off as the compressed white dwarf. These following examples are probably similar or perhaps representing a slightly smaller version of what the Sirius star/solar system looked like once Sirius B had started turning itself from an impressive red supergiant and suddenly into a white dwarf of perhaps 1/8th its previous mass, taking roughly 32~96,000 years for this accellerated mass shedding phase to happen. *A few tens of billions of years later is when such a white dwarf eventually becomes a black carbon dwarf, as kind of a black diamond spent star that our universe may or may not be quite old enough to display such examples. *http://en.wikipedia.org/wiki/Planetary_nebula *http://en.wikipedia.org/wiki/Helix_Nebula *http://en.wikipedia.org/wiki/Cat%27s_Eye_Nebula *http://apod.nasa.gov/apod/ap031207.html *http://www.uv.es/jrtorres/index6.html Betelgeuse has been a massive red supergiant at 20+ fold the mass of our sun, and likely worth somewhat better than two fold the mass of the original Sirius B. *Betelgeuse currently having expanded to 1000 solar radii and growing, it'll certainly become a truly impressive flashover whenever it runs out of helium and suddenly transforms itself into a white dwarf that’s nearly the size of Saturn. The soon to be renewed and greatly improved Hubble instrument should accomplish the improved spectrum coverage, along with improved resolution and several extra DB in dynamic range of imaging most everything, along with other existing and soon to be ESA deployed telescopes that are far superior yet, should give us even better composite examples of what Sirius B used to look like, and quite possibly our first light of Sirius C. This kind of public investment in astronomy should give some of us a better deductive kind of observationology, of somewhat less subjective interpretations as to what sort of stellar birth, growth and demise transpired right next door to us, as well as having unavoidably contributed to some of what our solar system has to offer. *However, perhaps there’s too much information already known about the Sirius star/solar system for the public to grasp, without causing more faith- based and political harm than good. *http://www.cosmicastronomy.com/oscillat.htm#sirius Just pretend that I never mentioned anything about this pesky Sirius star/solar system, and never mind the nearby nova when that happens. However, if any 5th graders are looking for a really nifty science project that'll seriously blow your teachers away and scare the hell out of most everyone else: you got my number. ~ BG |
