HD 76728 is a suspected astrometric binary [7] star system in the constellation Carina. It has the Bayer designation c Carinae; HD 76728 is the identifier from the Henry Draper catalogue. The visible component has a blue-white hue and is visible to the naked eye with an apparent visual magnitude of +3.84. [2] The system is located at a distance of approximately 320 light years from the Sun based on parallax, [1] and it is drifting further away with a radial velocity of around +25 km/s. [2] It is a candidate member of the Volans-Carina Association of co-moving stars. [8]
The visible component is an aging bright giant star with a stellar classification of B8/9II. [3] The spectrum of the star displays metallic lines of magnesium. [9] The Volans-Carina Association to which it belongs has an age of 90 million years. [8] The star has five [5] times the radius of the Sun and is radiating 449 [2] times the Sun's luminosity from its photosphere at an effective temperature of 11,880 K. [5]
