History of BD-3452+2543[]
About 121 billion years a yellow dwarf star formed from a decent sized nebulae, the same size and mass of the Sun it burned their fuel of hydrogen until abour 10.8 billion years later when it started to run out of Hydrogen and they started to contract under gravity until their cores reached 180,000,000 F and started to burn Helium into Carbon and Oxygen with this new source of energy they started to balloon out to red giant stars and stayed that way for about 80 million years until it ran out of Helium and started to puff out it's outer layers into a planetary nebula and it's core contracted under gravity until electron degeneracy pressure kicked in stopping it's contraction at about 12,400 km in diameter. This white dwarf star slowly cooled off and about 300 million years ago it stopped shining and became a black dwarf star which it is now.
