GENERAL FACTS

White Dwarfs are the remains of dead stars, the size that of the Earth and mass comparable to the Sun.

White Dwarfs are so dense that about a teaspoon full of white dwarf matter would weight 5.5 tons on our planet, Earth.

White Dwarfs are composed of hydrogen on the outer shell. Contains heavier elements, like Carbon.

GRAVITIES’ ROLE

White Dwarfs have low volume and high mass, which makes these stars extremely dense. The gravity balancing the outwards force in these stars is the “electron degeneracy pressure”.
