WebDec 28, 2024 · The mass of that white dwarf depends a lot on how massive the star was initially. The more massive the star, the more massive the white dwarf. But this leads to a paradox! The lowest mass white dwarfs we see are less than 0.3 times the Sun's mass; we call these Extremely Low Mass white dwarfs, or ELMs. WebMay 4, 2011 · White dwarf binary stars in general are extreme systems that radiate gravitational waves as they orbit each other. To balance the loss of this energy, the stars gradually come closer together ...
WebSep 4, 2009 · White dwarfs typically have masses in a narrow range centered at about 0.6 solar mass ( M⊙ ). Only a few ultramassive white dwarfs (mass > 1.2 M⊙) are known. Those in binary systems are of particular interest, because a small amount of accreted mass could drive them above the Chandrasekhar limit, beyond which they become … WebA white dwarf in a binary system is accreting mass from its companion star. What happens when the mass of the white dwarf exceeds 1.4 solar masses? A nova explosion occurs …
WebIf the mass of the white dwarf becomes greater than about 1.4 times the mass of the Sun—called the Chandrasekhar limit—it will collapse. In a binary star system this could happen if a nearby companion star dumps enough material onto a white dwarf to push it over the Chandrasekhar limit.
