V344 Carinae is a single[11] star in the southern constellation of Carina. It has the Bayer designation f Carinae, while V344 Carinae is its variable star designation. This star has a blue-white hue and is visible to the naked eye with an apparent visual magnitude that fluctuates around 4.50.[3] Historically, it was mentioned in the Almagest, suggesting that some time around 130 BCE it was brighter than its current magnitude.[12] This object is located at a distance of approximately 610 light-years from the Sun based on parallax.[2] The star is drifting further away with a radial velocity of around +27 km/s.[3]
This is a B-type main-sequence star with a stellar classification of B3V(n).[5] It is a Be star; a rapidly rotating star that is hosting a circumstellar disk of hot, decreted gas.[13] It is a photometrically variable Be star, having a brightness that ranges from 4.4 down to 4.51 in visual magnitude, and has been classified as a Gamma Cassiopeiae variable.[4] The star is 32[7] million years old and is spinning with a projected rotational velocity of 268 km/s.[9] It has seven[7] times the mass of the Sun and around 3.0[8] times the Sun's radius. The star is radiating 2,328[9] times the luminosity of the Sun from its photosphere at an effective temperature of 17,660 K.[9]
