Ellison's Star

Ellison's Star was a binary star in the Orion Arm of the galaxy. It was composed of a white dwarf and a small companion star.

It was known as the largest catastrophic variable star in the Orion Arm of the galaxy.

History
The lost, 21st century multi-generation Earth spaceship Wanderer was discovered 13 months away from the pull of Ellison’s Star. Gravity from the binary would divert the ship’s course toward Polo's Bolos and the galactic whirlpool. The USS Enterprise (NCC-1701) mounted a rescue operation in the year 2267. Pavel Chekov determined how to divert the ship’s course so that the gravity of Ellison's Star would be used as a slingshot to propel the ship onward to Malcor's Pride, a planet with a Federation colony. 


 * The term catastrophic variable was not a type of variable star used in 21st century astronomy. However, a cataclysmic variable that was not a supernova was a binary star system in which a white dwarf orbited so closely that it drew matter away from the smaller second star.
