A white dwarf is a dwarf star and the 'white' that was added to its name was just because, the few dwarfs that were found during their discovery appeared white--I'm not kidding, that's true.Do you know how dense a typical white dwarf can get?Well, if you don't, I can answer it for you: they appears in the size of our earth containing almost the entire mass of our sun. That's too much right?Because of their smaller size and heavier mass these stars are extremely denser and compact objects having the average density approaching 1,000,000 times that of water.To help you understand the way in which a normal star turns in to a compact white dwarf, let me explain to you the typical life cycle of a typical star.A star takes birth when large amounts of near by gaseous particles--hydrogen atoms--attracted towards each other through the gravitational force, gets collided and coalesce--after much needed collisions--with each other to produce large quantities of heat along with some heavier compounds. The heat that got released during this process is much like a controlled hydrogen explosion, and is in fact responsible for the star to shine so brightly up in the space.This heat got ...
