another thing, a white dwarf can go supernova if its a binary star and sucks up enough matter from its neighboring star. after it gets aproxamatly 1.5 solar masses, it goes KABLOOIE! but this is probably not the case
That's a different type of supernova than the one depicted.
Yeah. Capella was an artificially induced type II supernova, while what you're talking about, Paladin, is a type I supernova. Totally different. Capella A, being a fairly average-sized (okay, about 12x the Sun's radius and 2.7x Sun's mass) yellow star, isn't naturally capable of either. However, Capella B is about the same size as Capella A, and could potentially induce a supernova if the two were to mingle a little too closely, which they might, considering the fact that they orbit only 100 million km away from each other. The second pair of stars in the Capella system are just a couple brown dwarfs orbiting A and B at a distance of about 10,000 AU.
Of course, in-game stars aren't the same as real stars. [V] didn't really check their stars to make sure they're depicted correctly. I've noticed that the mediavps, however, are trying to fix that with their backgrounds. They got Ross 128 right, anyway (small red star, great lighting for taking on the remnants of the Lucifer's armada).
