17 Sep 2001 | Subject: | astro-ph | Affiliation: | SNU), William H. Waller (TuftsU), Joel Wm. Parker(SouthwestRI), Eliot M. Malumuth(NASA/GSFC), and Paul W. Hodge(UWashington | Abstract: | We present a photometric study of the stars in ionizing star clusters embedded in several giant HII regions of M33 (CC93, IC 142, NGC 595, MA2, NGC 604 and NGC 588). Our photometry are based on the HST-WFPC2 images of these clusters. Color-magnitude diagrams and color-color diagrams of these clusters are obtained and are used for estimating the reddenings and ages of the clusters. The luminosity functions (LFs) and initial mass functions (IMFs) of the massive stars in these clusters are also derived. The slopes of the IMFs range from Gamma = -0.5 to -2.1. It is found interestingly that the IMFs get steeper with increasing galactocentric distance and with decreasing [O/H] abundance. | Source: | arXiv, astro-ph/0109258 | Services: | Forum | Review | PDF | Favorites |
