On one star chart, a star designated Ellison was noted as being spectral class R/N/S with absolute magnitude 9+, having one planet, and being proximate to the Pelagic Planet. (ST reference: Star Trek Maps)
- Ellison may or may not have been Ellison's Star, though both were probably homages to Harlan Ellison.
The lost, 21st century Earth colony generational ship 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 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. (TOS novel: The Galactic Whirlpool)
- 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.
