NGC 6231 (= OCL 997)
Discovered (before 1654) by Giovanni Hodierna (list I, #7)
Discovered (1678) by Edmond Halley
A 3rd-magnitude open cluster (type I3p) in Scorpius (RA 16 54 09.8, Dec -41 49 30)
Per Dreyer, NGC 6231 (= Halley, Lacaille's list II #13, Dunlop #499, 1860 RA 16 44 15, NPD 131 33.6) is "cluster, bright, considerably large, pretty rich, stars from 10th to 13th magnitude". (Note: See Hodierna for a discussion of why he was not credited with the discovery of any NGC object. His list I was for visible groups of stars, so he must have seen that this object consisted of individual stars.) The position precesses to RA 16 54 04.0, Dec -41 47 50, a little over 2 arcmin northwest of the currently accepted position of the cluster, but still well within its central condensation, so the identification is certain. NGC 6231 is part of the Scorpius OB association, which consists of multiple clusters of very young stars. NGC 6231's hottest star, ζ Scorpii, is spectral type O8. Having a Main Sequence star of this high brightness and temperature implies a cluster age of just over 3 million years. The cluster is about 6000 light years away. Given that and its apparent size of about 15 arcmin, it is about 25 light years in diameter. The region surrounding the cluster is filled with clouds of gas and dust, many of which are heated, lit and sculpted by the radiation of the stars in the cluster. |
