GA: CAPOS: Distance, reddening and global metallicity determination of Bulge Globular Clusters – Villanova

April 22 @ 11:45 am 12:00 pm CMT

Bulge Globular Cluster have always ben a challange for the determination of their distance and reddening. This is because they are affected by high differential reddening and strong field contamination. In addition, in most of the cases only the RGB is observed since SGB and MS are too faint. However, thank to the advent of new databases like GAIA and 2MASS, and to the development of more reliable stellar models, it is now possible to isolate the cluster from the field, to correct for the differential reddening and apply a proper isochrone fit to the RGBs in order to get cluster parameters. This is particularly important for the purpose of calculating their orbits.
