Star in the constellation Carina
This article is about D Carinae. For d Carinae, see
V343 Carinae .
HR 3159 is a single
[10]
star in the southern
constellation of
Carina , positioned near the southern constellation border with
Volans . It has the
Bayer designation D Carinae ; HR 3159 is the
Bright Star Catalogue designation. This object has a blue-white hue and is visible to the naked eye with an
apparent visual magnitude of +4.81.
[2] It is located at a distance of approximately 499
light years from the
Sun based on
parallax ,
[1] and is drifting further away with a
radial velocity of 22 km/s.
This object is a
B-type main-sequence star with a
stellar classification of B4V,
[3] which indicates it is undergoing
core
hydrogen fusion . The star has a radius of nearly four times the radius of the Sun,
[5] and over six
[4] times the
Sun's mass . Age estimates range from 17
[4] up to 176
[8] million years old, and it is spinning with a
projected rotational velocity of 43 km/s.
[6] It is radiating 912
[6] times the
luminosity of the Sun from its
photosphere at an
effective temperature of 16,983 K.
