... Bad Astronomy . ... Mad Science . ... City: Braintree State/Province: Mass. ... If one of the stars goes supernova, and the other has a higher density. ... When most people think of a supernova (SN), they picture a single massive star exploding. ... The way the physics works, if the supernova expels more than half the total mass of both stars combined, the two stars will fly apart. For example, let's say the star that blows up masses 10 times the Sun's mass, and the companion masses twice the Sun. ...

... We consider the astrophysical evolution of the Galaxy over large time scales, from early stages (an age of ~10 8 yrs) to the end of traditional stellar evolution (~10 11 yrs). ... In the model considered, the basic stages of Galactic evolution are as follows. ... Essentially all other basic parameters of the Galaxy vary little. ... The final "stellar epoch" in the life of the Galaxy is completed ~10 13 yrs after its formation, when the evolution of the least massive stars comes to an end. ...
