A white dwarf star, a dense ball primarily composed of carbon and oxygen atoms, is intrinsically the most stable of stars, as long as its mass remains below the so-called Chandrasekhar limit of 1. Supernovae were known to create subspace shock waves capable of collapsing a warp field, and an electromagnetic pulse capable of knocking out computers in Feb 13, 2014 · This means it is likely a second generation star, and its first generation progenitor ended in a supernova that wasn’t powerful enough to cast out significant quantities of iron. A white dwarf is what's left after a star the size of our sun has run out of fuel. First-generation stars formed shortly after the Big Bang and consist of primarily hydrogen and helium. The Earth could soon have a second sun, at least for a week or two. Sol will expand to a red giant, then dwindle to a white dwarf. In this two-star system, gravity causes the larger and fluffier star to give up mass to a smaller and denser white dwarf companion. A supernova is the colossal explosion of a star.
