Last Results from Project MASGOMAS (MAssive Stars in Galactic Obscured MAssive clusterS)
Abstract
We want to present our program MASGOMAS (MAssive Stars in Galactic Obscured MAssive
clusterS), with its objectives, methodology and first results. MASGOMAS is a compilation
of cluster candidates, from previous catalogue of galactic clusters (Bica et al. (2003);
Dutra et al.(2003) and Mercer et al. (2005)), obtained using 2MASS infrared photometry.
In order to increase the infrared information of the candidates, we completed
near-infrared photometry and H-, K-filter spectroscopy for 9 of them, concluding with an
full analysis of the stellar content for 3 of the candidates, deriving its distance,
differential extinction, minimum stellar mass and age. Our near-infrared data was also
complemented with SPITZER imaging of our candidates and visual spectroscopy for some
specific stars in each of the 3 published clusters.
