HD 4113 is a dual star system in the southern constellation of Sculptor. It is too faint to be viewed with the naked eye, having an apparent visual magnitude of 7.88.[1] The distance to this star, as estimated by parallax measurements, is 137 light years.[2] It is receding away from the Sun with a radial velocity of +5 km/s.[2]
The primary member of this system, component A, is a Sun-like G-type main-sequence star with a stellar classification of G5V.[1] Estimates of its age are five[1] to seven[3] billion years old, and it is spinning with a leisurely projected rotational velocity of 2.3 km/s.[1] The star is metal rich, with nearly the same mass,[3] radius, and luminosity[4] as the Sun.
Orbiting this star is a giant planet and a brown dwarf (HD 4113 C); the latter has been directly imaged. It also has a co-moving stellar companion, designated component B, which is a red dwarf with a class of M0–1V at an angular separation of Шаблон:Val. This angle is equivalent to a projected separation of Шаблон:Val.[1]
The most recent parameters for HD 4113 C as of 2022 come from a combination of data from radial velocity, astrometry, and imaging, showing that it is about 52 times the mass of Jupiter, and on an eccentric orbit with a semi-major axis of about 50.4 AU and an orbital period of about 348 years.[5]
Planetary system
On 26 October 2007, Tamuz et al. used the radial velocity method to find a planet with a minimum mass one and half times that of Jupiter orbiting at 1.28 AU away from HD 4113 A. The planet's orbit is highly eccentric.[6]
