HD 73267

Star in the constellation Pyxis

HD 73267 is a star in the southern constellation Pyxis, near the western constellation border with Puppis. It has an apparent visual magnitude of 8.889[2] and can be viewed with a small telescope. The distance to HD 73267 is 164 light years based on parallax, and it is drifting further away with a radial velocity of +51.8 km/s.[5] It has an absolute magnitude of 5.24.[6]

This object is a G-type main-sequence star with a stellar classification of G5V.[3] It is roughly eight billion years old with a near-solar metallicity and is spinning with a projected rotational velocity of 1.65 km/s,[3] giving it a rotation period of around 33 days. The star has 90% of the mass and size of the Sun.[2] It is radiating 78%[3] of the Sun's luminosity from its photosphere at an effective temperature of 5387 K.[2]

Planetary system

In October 2008, a candidate planet was discovered orbiting this star. This object was detected using the radial velocity method by search programs conducted using the HARPS spectrograph.[3] Subsequent analysis of collected data suggests the presence of an additional long-period planet in the system with at least 83% of the mass of Jupiter.[2] In 2022, the inclination and true mass of HD 73267 b were measured, and the presence of a second planet was confirmed using a combination of radial velocity and astrometry.[8]
