first observed in 1990, has very similar proper motion to the primary, meaning that it is indeed a companion. Designated HD 43587 B, the star was found to be a faint M-dwarf.
Because of the star's brightness and position in the vicinity of the constellation of Monoceros, HD 43587 A was selected as one of the primary COROT astroseismology targets, which would collect information on the star's internal properties.
Since the primary star is similar to the Sun and did not seem to have a close
