White dwarf star - Study guides, Class notes & Summaries

White Dwarf "Star" correct answers Result of the death of a low mass star The exposed core of a low mass star; -hot -dense -mostly carbon If there is no new energy production in a white dwarf, what prevents gravity from crushing it? correct answers Electron degeneracy pressure White dwarf "stars"- electron degeneracy pressure correct answers Electron degeneracy pressure will only hold up a star to about 1.4 solar masses, above that gravity will begin to win, resulting in the st...

White dwarfs: properties - Remaining cores of dead, low mass stars Electron degeneracy pressure supports them against gravity Slowly fade with time Sirius and its hot WD companion White dwarfs with same mass as Sun are about same size as Earth; slowly cooling Typical density 10^6 gram / cubic cm Higher mass white dwarfs are smaller Cannot be more massive than 1.4MSun, the Chandrasekhar limit WDs in binaries: nova, supernova Type I - Mass falls toward white dwarf from binary companion ...
