Where can I access data on white dwarf stars? I need to find the mass and temperature of these stars.?

Question

The WD stars all have a mass between .7 and 1.4 solar mass and range in temperature between a few thousand degrees and 25,000 degrees. I am looking for data that shows how mass and temperature are related in these type of stars.

Answer 1

Mass and temperature are essentially unrelated in white dwarf stars. They're held up by electron degeneracy pressure, and so the thermal pressure caused by their temperature is not significant. A white dwarf will maintain a constant mass as it cools to zero temperature.

Answer 2

various sturdy solutions here, yet i presumed i might sparkling one element up: this is not precisely impressive to declare that white dwarfs can't substitute into black holes. actual, a white dwarf left to its very own will in simple terms persist, ever so slowly cooling down over billions and billions of years. yet maximum stars interior the galaxy (and it stands to reason in different galaxies, too) are in binary (or extra) structures. if one celebrity of a binary device evolves right into a white dwarf, the variations that take place in mass and composition of the celebrity can severely substitute the orbital dynamics of a 2-celebrity device. they could be altered so severely that the white dwarf celebrity is in a position to accrete rely from its companion. yet a white dwarf is held up by potential of electron degeneracy rigidity, which could basically face up to lots inward rigidity because of gravity. it somewhat is the reason white dwarfs can't exist over a undeniable mass, stated as the Chandrasekhar decrease. So if a white dwarf accretes sufficient mass from its companion to surpass that decrease, something's gotta provide. the white dwarf will implode first, then explode because of fact the helping mechanism for the celebrity is conquer. the violent implosion of the white dwarf could nicely be sufficient to create a neutron celebrity, or according to danger a stellar-mass black hollow. this way of adventure is stated as a sort I-a supernova, and it somewhat is actual the main easy style of supernova it extremely is stated.

Answer 3

Run to the nearest library and look for a Hertzsprung-Russell giagram. It will show you exactly what you are asking.

Answer 4

all you have to do is type in "white dwarf stars" into your search engine and you will get 1,130,000 results .
