Búsqueda y análisis de asociaciones estelares en NGC247

Abstract

From ACS/HST observations, available in the Space Telescope database, the search and analysis of young stellar associations in the galaxy NGC247 have been carried out. The Path Linkage Criterion was used for the detection, identifying 147 young stellar groups. Thanks to the ACS high spatial resolution, it was possible to detect the individual components of each groups allowing the construction of the radial density profiles, the photometric diagrams decontaminated by field stars, and the initial mass function. Thus it has been possible to identify some basic properties of the groups, such as sizes, masses, etc. We also performed a global study of the behavior of these associations in the galaxy.
