HD 83183 is a single [9] star in the southern constellation of Carina. It has the Bayer designation h Carinae, while HD 83183 is the star's identifier from the Henry Draper catalogue . The star is blue-white in hue and is faintly visible to the naked eye with an apparent visual magnitude of 4.08. [2] It is located at a distance of approximately 1,330 light years based on parallax, [1] and is drifting further away with a radial velocity of +18 km/s. [2] O. J. Eggen identified it as a member of the Pleiades group of co-moving stars. [10]
This object is a massive bright giant star with a stellar classification of B5 II. [3] It is 25 [4] million years old and is spinning with a projected rotational velocity of 19 km/s. [7] The star has 9 [4] times the mass of the Sun and about 18 [5] times the Sun's radius. It is radiating 11,634 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 14,300 K. [6]
