A retrospective look at Sirius B in its red supergiant phase
On May 12, 7:20*pm, BradGuth wrote:
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. *However, since this topic is officially Usenet/newsgroup banished and otherwise taboo/ nondisclosure rated, perhaps we'll just have to forget that anything of the cosmic and stellar sort of creation process ever happened. 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. 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...php?t=actu&id_... *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...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 Interesting, that not even as of 20 some odd ice-ages ago, or that of merely 200 million years ago, are we aware of exactly where the hell our 12 mass Sirius star/solar was located, as of just shortly after being created from a truly massive molecular dense enough cloud of perhaps at least 12e3 soar masses. So, where exactly did the rest of that stellar worthy molecular cloud of mostly hydrogen and helium go, and why did it just as suddenly leave us in its dust (so to speak), with no trace of itself. Do such terrific molecular and thus star making clouds just come and go as they please? ~ BG |

What is making the little but unmistakable wobble? (a .06M black hole, a neutron star, a black dwarf planetoid/asteroid, perhaps that of a brown dwarf, or is it our sun and Jupiter?) ~ BG |

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 including nifty Earth science pertaining to out magnetosphere and solar wind, along with another darn good option of using the Earth-moon L1 (Selene L1) location instead of the polar LEO that’s currently in use by the old existing TRACE. At 1% the cost of Hubble, either of two TRACEx100 (100x greater resolution than our existing TRACE), plus added dynamic range and possibly even a third TRACEx100 could also perform multiple OCO duties, as well as some limited Selene/moon related science and even basic astronomy functions from within Selene L1. Perhaps with some luck and composite imaging from the renewed and greatly improved Hubble we’ll locate the massive cloud of molecular gasses that gave such a vibrant birth to the nearby Sirius star/solar system, and thereby obtaining a better understanding as to the most recent evolution of stars, and essentially of everything else (including ourselves). The whole package deal of creating and deploying 3 TRACEx100s should come in under $200M, and it’s nearly all Earth, moon and solar related science to boot. The original creators of TRACE could be contracted to create these new and improved TRACEx100, which should easily exceed a decade or two in their deployed operation without further attention. http://helios.gsfc.nasa.gov/trace_mosaic.html ~ BG |

The hunt for Sirius C is about to get more interesting, with three new ESA deployed astronomy missions, and our renewed Hubble upgraded to within a few years of being the best of technology that it can be, as such should make detecting everything from tiny neutron stars to black holes a whole lot more doable.

With proper instruments in orbit (some of which already exist) or otherwise as best situated within Selene L1, via observationology we could deductively interpret in order to better understand and objectively quantify this ongoing loss. The OCO mission was also supposed to identify certain gaseous elements related to global dimming and greenhouse heating, as well as accurately map their terrestrial origin, but that got terminated just in the nick of time. ~ BG |

Come on folks, tell us where that great molecular cloud is that so recently created the Sirius star/solar system.

Tell us why the truly substantial mass of the hydrogen and helium flashover of Sirius B into becoming an impressive white dwarf didn't affect us. ~ Brad Guth Brad_Guth Brad.Guth BradGuth BG / “Guth Usenet” |

As of 250~300 million years ago, Eden/Earth and our entire solar system became surrounded and otherwise cosmic saturated within the exact same molecular cloud that gave birth to the massive and extremely vibrant Sirius star/solar system. Yet for some odd reason this doesn’t seem to bother anyone, nor the fact that we can’t manage to rediscover any remainder of this horrific molecular cloud. Is it just me, or do we think there’s something more than a little fishy going on? What would happen to our terrestrial environment if our solar system once again became surrounded by any significant portion of the same 12,000 some odd solar masses worth of such a cosmic molecular cloud? We’re told by the published experts in cosmology and astrophysics that 12,000 solar masses is a conservative molecular cloud for having given birth to a 12 solar mass star system, such as the original Sirius, whereas more than likely it would have been a cloud of 24,000~64,000 solar masses. ~ Brad Guth Brad_Guth Brad.Guth BradGuth BG / “Guth Usenet” |
