HR 4102
I Carinae is a single, yellow-white hued star in the southern constellation Carina. It is a fourth magnitude star that is visible to the naked eye. An annual parallax shift of 61.64 mas provides a distance estimate of 62 light years. It is moving closer with a radial velocity of −5 km/s, and in an estimated 2.7 million years will pass within of the Sun. In the next 7500 years, the south Celestial pole will pass close to this star and Omega Carinae (5800 CE). Gray et al. (2006) gave this star a stellar classification of F3 V, indicating it is an F-type main-sequence star that is generating energy through hydrogen fusion at its core. It is younger than the Sun with an estimated age of 977 million years, and is spinning with a projected rotational velocity of 51.6 km/s. The star has 1.4 times the mass of the Sun and is radiating 5.56 times the Sun's luminosity from its photosphere at an effective temperature of around 7,017 ...

Carina (constellation)
Carina ( ) is a constellation in the southern sky. Its name is Latin for the keel of a ship, and it was the southern foundation of the larger constellation of Argo Navis (the ship ''Argo'') until it was divided into three pieces, the other two being Puppis (the poop deck), and Vela (the sails of the ship). History and mythology Carina was once a part of Argo Navis, the great ship of Jason and the Argonauts who searched for the Golden Fleece. The constellation of Argo was introduced in ancient Greece. However, due to the massive size of Argo Navis and the sheer number of stars that required separate designation, Nicolas-Louis de Lacaille divided Argo into three sections in 1763, including Carina (the hull or keel). In the 19th century, these three became established as separate constellations, and were formally included in the list of 88 modern IAU constellations in 1930. Lacaille kept a single set of Greek letters for the whole of Argo, and separate sets of Latin letter designa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
