HD 104067 is a star with a planetary system in the southern constellation of Corvus. It has an apparent visual magnitude of 7.92[2] which is too faint to be visible with the naked eye. The distance to this star is Script error: No such module "convert". based on parallax. It is drifting further away with a radial velocity of +15 km/s.[1]
This is an ordinary K-type main-sequence star with a stellar classification of K3V.[3] It is a moderately active star[8] with an age of roughly five billion years. HD 104067 is spinning with a projected rotational velocity of 2.5 km/s,[4] giving it a rotation period of approximately a month.[3] The star has 82% of the mass and 77% of the radius of the Sun.[4] It is radiating 31%[5] of the Sun's luminosity from its photosphere at an effective temperature of 4,942 K. The metal content of this star is close to that in the Sun.[4]
Planetary system
HD 104067 has been observed as part of the HARPS planet-finding survey since 2004. The detection of an exoplanetary companion using the radial velocity method was announced in 2011. This sub-Saturn planet, HD 104067 b, has at least 0.2 times the mass of Jupiter and takes 55.8 days to orbit the star at a distance of Script error: No such module "val"..[8] The discovery of a second, Uranus-mass planet, HD 104067 c, was announced in 2024 based on HARPS and HIRES data. TESS observations also show evidence of a third candidate planet, slightly larger than Earth and orbiting closer to the star than the other two planets, with a period of just 2.2 days. Modeling suggests that this inner planet candidate may experience significant tidal heating.[6]
