IC 2714 is an open cluster in the constellation Carina. It was discovered by James Dunlop in 1826.[5] It is located approximately 4,000 light years away from Earth, in the Carina–Sagittarius Arm.[6]

Characteristics

It is a rich to moderately rich, intermediate-brightness, detached cluster with Trumpler type II2r or II3m.[5] There are 494 probable member stars within the angular radius of the cluster and 215 within the central part of the cluster.[7] The tidal radius of the cluster is 6.3 - 8.7 parsecs (21 - 28 light years) and represents the average outer limit of IC 2714, beyond which a star is unlikely to remain gravitationally bound to the cluster core.[3] The core of the cluster is estimated to be 5.9 light years across.[7]

The brightest stars of the cluster are of 11th magnitude and the brightest main sequence stars are of late B of A type.[8] Two blue stragglers have been detected in the cluster,[9] one variable star and eleven red giants.[8] The turn-off mass of the cluster is estimated to be at 3.1 M☉.[4] The cluster has the same metallicity as the Sun.[10]
