The history of star formation in the Galactic young open cluster NGC 6231
Abstract
We study the star formation history of the galactic young open cluster NGC 6231 using new, deep, wide-field BVRI imaging. Contrary to previous suggestions, we do not find a lack of low-mass cluster members; our derived mass function is compatible with a Salpeter IMF. The star formation history of NGC 6231 appears to be bi-modal, with a first wave of star formation activity 3-5 Myr ago, followed by a new generation of stars forming ~ 1 Myr ago.
