Star in the constellation Carina
This article is about t
1 Carinae. For t
2 Carinae, see
HD 92397 .
HD 92063 is a single
[8]
star in the southern
constellation of
Carina . It has the
Bayer designation t1 Carinae , while HD 92063 is the star's identifier from the
Henry Draper Catalogue . This is a suspected
variable star
[4] and is visible to the naked eye with an
apparent visual magnitude of 5.08.
[2] The star is located at a distance of approximately 246
light years from the
Sun based on
parallax , but is drifting closer with a
radial velocity of −10 km/s.
[1] Although it appears at the edge of the
Carina Nebula , it is much closer than the nebula. It is also not considered a member of the nearby Alessi 5
open cluster of stars.
[9]
This is an aging
K-type
giant star with a
stellar classification of K1III,
[3] having exhausted the supply of hydrogen at its
core then cooled and expanded off the
main sequence . At present it has 14
[1] times the
radius of the Sun . The star is radiating 72
[1] times the
Sun's luminosity from its enlarged
photosphere at an
effective temperature of 4,520 K.
