HD 29587

HD 29587 is a Sun-like[7] star with a candidate brown dwarf companion[8] in the northern constellation of Perseus.

The star is moving away from the Earth with a heliocentric radial velocity of +113 km/s,[1] having come to within 55.8 ly some 148,000 years ago.

[2] It is a hyper-velocity halo[7] star moving at a rate of 170 km/s relative to the local standard of rest.

It has 78% of the mass of the Sun and is radiating 80% of the Sun's luminosity from its photosphere at an effective temperature of 5,709 K.[3] Formerly an IAU radial velocity standard, this star was found to have a variable radial velocity due to a suspected orbiting companion.

The secondary object most likely has a mass in the range 41.0–97.8 MJ, making it a probable brown dwarf.
