Ultraviolet studies of the young populous cluster NGC 2100 in the LMC.
Abstract
Stars in the populous young cluster NGC 2100 were observed with IUE in the low resolution mode. Color excesses, effective temperatures and luminosities were determined for eight stars in the cluster. A comparison of observed and model atmosphere energy distributions shows that the Nandy et al. (1981) average LMC extinction curve does not give good matches for the cluster stars. For most of the cluster stars no hump in the extinction at 2200 A is observed and too little flux is observed between 1400 and 2000 A. Masses between 15 and 30 solar masses were found for the stars and an age of about 6 million years. Two stars, b27 and C1, may have an age of up to 12 million years.
