HD 88955
Star in the constellation Vela
HD 88955 is a single,[10] white-hued star in the southern constellation of Vela. It can be viewed with the naked eye, having an apparent visual magnitude of 3.85.[2] The distance to HD 88955 can be determined from its annual parallax shift of 32.7 mas,[1] which yields a separation of 100 light years from the Sun. It is moving further from the Earth with a heliocentric radial velocity of +7 km/s.[4] Bayesian analysis suggests HD 88955 is a member of the Argus Association,[11] a group of co-moving stars usually associated with the IC 2391 open cluster.
This is an A-type main-sequence star with a stellar classification of A2 V.[2] It is about 410[5] million years old with a projected rotational velocity of 100 km/s.[8] The star has 2.17[5] times the mass of the Sun and 2.11[5] times the Sun's radius. It is radiating 23[5] times the Sun's luminosity from its photosphere at an effective temperature of 9,451 K.[6] An infrared excess has been detected from HD 88955, which analysis suggests is a (3.6±3.0)×10−7 M🜨 debris disc with a mean temperature of 138±21 K orbiting the host star at an average distance of 19.3±5.7 AU.[12]
