For tao Redkat & BAW..
 
Just WTF is a Champagne Supernova?




Please splain!!!




:lol:

BAW 02-16-2007 03:19 AM

omg, we are SO kicking your ass!!! :lol: :madwife:

redkat 02-16-2007 03:36 AM

I love oasis even more now and I'd almost forgot about tao
 
:lmao: you thought I was drunk didn't you!

It promises to revolutionize current thinking about the physics of supernovae because of its highly unusual nature, in particular the mass of its progenitor. According to the current understanding, white dwarf stars go supernova when they approach 1.4 solar masses (1.4 times the mass of the Sun), termed the Chandrasekhar limit; the explosion occurs when the central density grows to a critical 2 x 109 g/cm3. The mass added to the star is believed to be donated by a companion star, either from the companion's stellar wind or the overflow of its Roche lobe as it evolves. However, the progenitor reached 2 solar masses before exploding, more massive than thought possible. The primary mechanism invoked to explain how a white dwarf can exceed the Chandrasekhar mass is unusually rapid rotation; the added support effectively increases the critical mass. An alternative explanation is that the explosion resulted from the merger of two white dwarfs. The evidence indicating a higher than normal mass comes from the light curve and spectra of the supernova --- while it was particularly overluminous the kinetic energies measured from ejecta signatures in the spectra appeared smaller than usual. The explanation is that more of the total kinetic energy budget was expended climbing out of the deeper than usual potential well.

This is important because the brightness of type Ia supernovae was thought to be essentially uniform, making them useful "standard candles" in measuring distances in the universe. Such an aberrant type Ia supernova could throw distances and other scientific work into doubt, however the light curve characteristics of SNLS-03D3bb were such that it would never have been mistaken for an ordinary high-redshift Type Ia supernova.

Need a little time to wake up, night_and_day66? :scratch:

OASIS SUCK!

BAW 02-16-2007 11:10 AM

omg, your sig! :lmao: :madwife:


We should have told the bouncer to throw you out too last night :angry:

ok, fair enough...now where does the champagne come in? huh? huh??

Your intelligent and lengthy reply is merely a distraction to the fact that OASIS STILL SUCKS ASS!


And you were drunk, dont you forget you pulled your boobs out and sang
"My Humps" while springing from stool to stool?


Or was that a dream i had? :hmm:

Zoots 02-16-2007 11:13 AM

Carlos' sig space has become like a newspaper.. with the latest interference headlines :drool:

RedRocksU2 02-16-2007 11:15 AM

btw, I need more sleep:crack:
