Abstract

As part of new project in the framework of the activities of the subject `Astrofísica General} (FaMAF, UNC), we present astrophysical parameters of open clusters located in the third and fourth Galactic quadrant: NGC 2243, NGC 2439, Pi 12, Tr 13 and NGC 5168. Based on Gaia DR3 photometric data and fitting theoretical isochrones to the color-magnitude diagrams (GBP-GRP, G), we derived ages, metallicities, distances and colour excess E(GBP<-GRP) for these fairly known open clusters. Also, we present the start of a new project consisting of the systematic study of open clusters observed from Estación Astrofísica de Bosque Alegre (OAC, UNC). These photometric data will allow us, on the basis of colour- magnitude diagrams, to analyse these stellar aggregates homogeneously.
