Red giant stars are many, and yet 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. *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 visual capability, in
that other creatures seem to have a far wider visual spectrum
capability that includes some UV and IR without any applied
technology)

Sirius B could have been much like an image of Mira A, except a whole
lot larger (5001000 solar radii), as viewed in visible and near IR as
that of a red supergiant star.

There are many possibilities, as for how Sirius B used to function as
a truly massive (9 solar mass) star, thereby extremely hot and fast
burning prior to becoming a red supergiant, creating an impressive
planetary nebula phase before ending as the little white dwarf. *For
all we know Sirius B was even a variable kind of red giant and then
perhaps a slow nova flashover phase prior to finishing off as the
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 into a white dwarf of perhaps 1/8th its original mass,
taking roughly 64~96,000 years for this explosive mass shedding phase
to happen. *A few tens of billions of years later is when such a white
dwarf eventually becomes a black dwarf, kind of black diamond spent
star, in that our universe may or may not be quite old enough to
display such examples.

Betelgeuse has been a massive red giant at 20+ fold the mass of our
sun, and likely worth somewhat better than two fold the mass of the
original Sirius B, as Betelgeuse currently having expanded to 1000
solar radii and growing, it'll certainly become a truly impressive
nova whenever it transforms into a white dwarf that’s nearly the size
of Saturn.
The soon to be renewed and improved Hubble should accomplish the
improved spectrum, resolution and several extra DB in dynamic range of
imaging most everything, along with other existing and soon to be
deployed telescopes should give us even better composite examples of
what Sirius B used to look like. *This may give some of us a better
interpretation as to what transpired right next door to us, as well as
having unavoidably contributed to some of what our solar system has to
offer.
Perhaps there’s too much information about the Sirius star/solar
system for the public to grasp without causing more faith-based harm
than good.

There’s more to creating a solar system than meets the naked eye,
because not everything we see is via natural cosmic perfection (in
most every instance it’s random happenstance, and in some cases it’s
looking rather complex and/or of weird physics that’s far from
perfection, and only getting worse as galaxies merge).
Here’s my 3nd or 4th revised/updated reply to wizard Paul A (pnals),
as being another one of our resident diehard anti-revisionist, plus
otherwise this effort is for anyone else without an original deductive
thought or a lose cannon to his/her name.

Well, this statement is nonsense. Sirius A & B are a physical pair,
they orbit each other, and this means that in all probability they
were born at about the same time. This system is approximately
200-300 million years old, which is very young in astronomical terms,
and much younger than our sun, which is about 5 billion years old.
Interestingly, Sirius B was once the larger and probably brighter of
the two, but this meant that it evolved faster and today has already
proceeded to the white dwarf stage, whereas Sirius A is still in the
prime of its life. Eventually it, too, will become a white dwarf and
the system will be perhaps something like this one;

So, you're another one of the ultra singular BB creation and forever
expansion purest at heart, that doesn't believe there's ever anything
rogue going on, no such mergers or encounters of any importance taking
place and otherwise nothing of significant cosmic interactions of any
kind taking place, and the Great Attractor plus a good number of
colliding galaxies and of those about to merge simply do not exist.
Well, aren't you special, especially since our Milky Way is likely
comprised of two galaxies as is, and at least part of our galaxy is
about to merge with part of the Andromeda galaxy. (gee whiz, what
could possibly go wrong?)
There is nothing special about the Sirius system, there are thousands
and thousands of others out there just like it.
But those other ones of any significant mass were not suddenly created
as situated right next door if not on top of us.
Sure, rogue events might happen here and there, but these would be
mostly in globular clusters where such chance encounters would be more
likely to occur.

I’ve always agreed and having frequently argued that binary and even
trinary star systems are pretty much the cosmic norm. However, we
have to realize what you are saying is that a truly impressive multi
light year expanse of highly dynamic and thus hugely volumetric zone
of sufficient cosmic saturated gas, having existed as of merely 300
million some odd years ago, of mostly hydrogen and otherwise helium
and a few other molecular elements that was sufficiently star creation
worthy, as situated right next door to our solar system, whereas
instead of such gas being gathered up by our nearby and well
formulated tidal radius of more than sufficient gravity influence
exceeding light years, having instead independently formulated itself
into a nifty pair of truly massive stars (Sirius B of 9 solar masses
and Sirius A of 2.5 solar masses, plus having created at least a
third significant other body of .06 solar mass as Sirius C).
Did I get that interpretation about right?
Considering everything about our universe and local galaxy had to have
been more compact and otherwise closer as of 300 million years ago,
we're talking about a sufficient volumetric kind of cosmic gaseous
cloud of roughly 12 solar masses (assuming 100% combining efficiency),
as happening right next door if not damn near on top of and/or easily
including us, and it just doesn't add up as to why that horrific and
nearby amount of such electric charged hydrogen wasn't the least bit
attracted to our pre-existing solar system mass of 2e30 kg. I mean to
ask, what the hell was wrong with all of that available hydrogen,
helium and the assortment of other elements, as why exactly didn’t we
get our fair share if we were here first?
In order to muster up 25e30 kg, that’s only 330 cubic light years of
1e-18 bar molecular hydrogen that’s supposedly worth 0.0899e-18 kg/m3,
though actually it’s of less cosmic ISM density because of such gas
being hot as hell and continually tidal force pulled apart or simply
diverted by the surrounding gravity of other nearby stars (such as our
sun), so let us make it worthy of at least 3300 ly3, and that’s only a
gaseous populated sphere of 18.5 light years diameter at 100% stellar
formation efficiency, and since we can safely say this star creating
process is never that good, so perhaps 33,000 ly3 as a collective
gravitational collapse worthy sphere of 40 ly is more like it.
The “Jeans Mass” for accommodating a sufficient “triggered star
formation” is suggesting much greater solar mass ratios of at least
1000:1 64,000:1 required for feeding the gravitational accretion
collapse process, of which easily puts our solar system smack within
the central realm of whatever culmination of cosmic matter and
formulating events that created Sirius ABC, making our 4+ billions of
years older solar system very much involved within that same stellar
birthing era.

Were we actually that close to such a complex and absolutely vibrant
stellar birth as of 300 million years ago, plus then having Sirius B
going red-supergiant and then slow nova postal on us, and yet somehow
we remained unaffected? (Paul and others, are you joking?)
Perhaps if something of initial mass were to arrive and/or merge into
a smaller but sufficient molecular cloud of mostly hydrogen and helium
that would have still included our solar system, such as a brown dwarf
of 10~100 Mj, or possibly a small antimatter black hole could have
been the stellar seed, but perhaps that kind of reverse-nova or anti-
nova process too should have adversely affected our solar system that
was likely situated within that very same molecular cloud.
Within many complex theories to pick from http://
www.answersingenesis.org/tj/v11/i2/dinosaur.asp, supposedly the final
straw of our dinosaur extinction process took place as of merely 65
million years ago, of which seems to suggest the nearby red-giant and
subsequent slow nova of Sirius B (our second sun) suddenly becoming a
white dwarf and having lost its tidal radius grip on whatever planets,
planetoids and moons would have been a most likely contributor of this
otherwise robust biodiversity demise, that by rights should have
otherwise stood the test of time.
It seems highly unlikely that our solar system was unaffected by the
nearby Sirius star/solar system formation and of its subsequent red
supergiant demise in becoming a white dwarf. Clearly no one cosmic
and/or terrestrial event caused the great extinction process, although
physical impacts derived from the sudden demise of the Sirius B solar
system (perhaps including that of obtaining Venus plus an icy Selene
as our moon) would certainly have been trauma worthy of creating
thermal extremes and otherwise geophysically catastrophic towards
finishing off most of whatever was left of such robust life on Earth.
A 100% BradGuth theory: Prior to the final lithobraking, Eden/Earth
tilting, Arctic ocean basin creating and quite a few antipode mountain
producing kind of nasty sucker-punch encounter with an extremely icy
Selene, as of roughly 12,900 +/- some odd hundreds of years ago
(according to David Fastovsky), and subsequently as having become our
Selene/moon, whereas chances are there were a few orbital near miss
opportunities for creating some truly impressive tidal gravity
exchanges. By 11,711 BP the new seasonally improved skies were
finally clearing, and the last ever ice-age thaw from which Eden w/
moon is ever going to see was on. (trust me, there are a good number
of public owned and fully public funded supercomputers that could have
run this complex 3D interactive simulation as of a more than decade
ago)
Of course, here in Google/NOVA Groups (Usenet/newsgroups) land of
forever cloaking on behalf of their ultimate Dark Side and mostly
insurmountable naysayism plus mainstream obfuscation, denial and above
all consistently anti-revision mindsets, you’d think there would be a
little what-if elbow room for the give and take of fresh ideas,
especially since so much of astrophysics upon what we thought we knew
has been recently tossed out the proverbial window. Meanwhile, the
most vibrant and interesting star system that’s situated right next to
us remains as oddly taboo/nondisclosure rated, as though our NASA had
once landed on it, or that it’s hiding OBL plus Muslim WMD along with
all of those SEC red-flag reports that were never acted upon, and of
course those 700 large and clearly marked NASA/Apollo boxes of mission
related R&D, as-built documentation, plus loads of critical systems
and science data that seemed to vanish into thin air.
Perhaps there’s simply too much information about the Sirius star/
solar system for the public to grasp without causing more faith-based
harm than good.

BTW; I find that creation, intelligent design and natural evolution
can safely coexist most anywhere, except here on Eden/Earth. Seems
there’s an all or nothing terrestrial mindset that can only insure war
upon war as the one and only basis for settling anything, along with
the environment be damned and otherwise it’s nearly every man, woman,
child and creature for themselves (at this point it’s mostly the bugs,
microbes and viruses that are winning, because their DNA has mutated
for the better and they’ll be here and tougher than ever long after
we’re gone), while the human species of evolution seems only to flat-
line or evolve in the wrong direction, especially for a planet that’s
losing far more mass than it gains, and a badly failing geomagnetic
force that's going south, so to speak
