VLT-FLAMES observations of young stellar clusters in the Magellanic Clouds
We introduce our VLT-FLAMES survey of massive stars in the Galaxy and the Magellanic Clouds, giving details of the observations in our younger fields in the LMC and SMC. In particular we highlight a new O2.5type star discovered in N11, and Be-type stars in NGC 346 with permitted Fe II emission lines in their spectra. We give an overview of the distribution of spectral types in these fields and ...
متن کاملYoung Clusters in the Magellanic Clouds II
We present the results of a quantitative study of the degree of extension to the boundary of the classical convective core within intermediate mass stars. The basis of our empirical study is the stellar population of four young populous clusters in the Magellanic Clouds which has been detailed in Keller, Bessell & Da Costa (2000). The sample affords a meaningful comparison with theoretical scen...
متن کاملOld and Intermediate-age Stellar Populations in the Magellanic Clouds
The Magellanic Clouds have galactocentric distances of 50 and 63 kiloparsecs, making it possible to probe the older populations of clusters and stars in some detail. Although it is clear that both galaxies contain an old population, it is not yet certain whether this population is coeval with the date of formation of the oldest globulars in the Milky Way. The kinematics of this old population i...
متن کاملThe Magellanic Clouds Photometric Survey: the Large Magellanic Cloud Stellar Catalog and Extinction Map
We present our catalog of U , B, V , and I stellar photometry of the central 64 deg area of the Large Magellanic Cloud. Internal and external astrometric and photometric tests using existing optical photometry (U , B, and V from Massey’s bright star catalog and I from the near-infrared sky survey DENIS) are used to confirm our observational uncertainty estimates. We fit stellar atmosphere model...
متن کاملYoung stellar populations in the Magellani Clouds
We discuss the young population of stars and clusters in the Magellanic Clouds. We present the discovery of pre-main sequence candidates in the nebula N 11 in the Large Magellanic Clouds. The comparison of the Colour-Magnitude diagram with pre-main sequence tracks and the presence of Spitzer objects YSO I and II suggest that the star formation has been active for a long period in the region, fr...
