History up until now of JS-2343+2345

About 10 billion years ago it formed from a nebula along with it's red dwarf star companion as a yellow dwarf star but with no planets, nothing of note happens until about 1 billion years ago when the star began to run out of Hydrogen in it's core and started to contract until the core of the star reached 180,000,000 degrees F and starting burning Helium into Carbon and Oxygen and this new source of energy started to balloon out the star into a red giant star coming within 12,000,000 km of swallowing it's companion, after about 100 million years it ran out of Helium and it started to collapse once again but this time it has run out of energy completely and started to contract and puff out it's outer layers into what is known as a planetary nebula and the core of the star contracted under gravity until electron degeneracy pressure kicked in stabilizing it and it stopped contracting at 13,000 km in diameter, a little larger than Earth but with about 300,000 times more mass than it even with all of that it barely harmed it's companion and that's what is now today.

The binary star system's future

  • In about 30 billion years the red dwarf star will start to die off and become a little larger and then blink out of existence into a white dwarf star like it's companion did about 30 billion years earlier.
  • The pair will slowly radiate away a lifetime of energy until about 90 billion years later when they stop shining altogether and become cold dead black dwarf stars.
  • About 12 billion years after they become black dwarfs a rogue star comes through about the size of the Sun disrupting their orbits around each other and get flung closer into a unstable orbit, they then after about 1,000 years in the unstable orbit collide and the impact gives off a little heat and it temporarily makes the resultant star a white dwarf star again but for only 3,000 years, and then it becomes a black dwarf star once more.
