IC 2714is anopen clusterin the constellationCarina.It was discovered byJames Dunlopin 1826.[5]It is located approximately 4,000light yearsaway from Earth, in theCarina–Sagittarius Arm.[6]

Characteristics

[edit]

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 brightestmain sequencestars are oflate BofA type.[8]Twoblue stragglershave been detected in the cluster,[9]onevariable starand elevenred giants.[8]Theturn-off massof the cluster is estimated to be at 3.1M.[4]The cluster has the samemetallicityas the Sun.[10]
