Star in the constellation Centaurus
HD 125288 is a single[9] star in the southern constellation of Centaurus . It has the Bayer designation v Centauri (lower case V); while HD 125288 is the star's identifier in the Henry Draper catalogue . The object has a blue-white hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.30.[2] Based on parallax measurements, it is located at a distance of approximately 1,230 light years from the Sun .[1] This is a candidate runaway star that is moving to the west and falling back into the Galactic plane .[5] It has an absolute magnitude of −3.56.[2]
This massive B-type supergiant star [3] has a stellar classification of B5Ib/II[4] or B6Ib.[5] It is around 37 million years old and has 8 times the mass of the Sun .[6] The star has expanded to 19[7] times the girth of the Sun and is spinning with a projected rotational velocity of 23 km/s.[3] It is radiating 806 times the luminosity of the Sun from its photosphere at an effective temperature of 7,081 K.[7]
In 2016, an asterism including HD 125288 (SAO 241641) was unofficially identified in honor of David Bowie .[10] [11]
