Chi 1 Orionis System

Exoplanetary Scratchpad [SysBP Img]

Chi 1 Orionis is also called Gl 222, HR 2047, and HD 39587. Nearby binary star system. A yellow dwarf star somewhat brighter than the Sun and a red dwarf. Because the red dwarf orbits 3.3 to 8.9 AU, the chances of a habitable planet are low. A member of the Ursa Major Moving Group. There is a theory that this star may have once been in a star system that includes HD 147513 A and B (which have a planet), which is part of the same moving group. When HD 147513 B went on to become a White Dwarf, material was sluffed off onto Chi 1 Orionis A, enriching it and causing it to become a "Barium Dwarf". Gravitational instabilities caused Chi 1 Orionis and HD 147513 systems to separate.
