Abstract

The present work performs an asteroseismic study of a gamma Doradus star member of the open cluster NGC 2506. This work conjugates the observational information of the star and the strong constraints imposed by the cluster membership, with the latest developed theoretical asteroseismic tools for the modelling of this type of objects, in particular the Frequency Ratio Method (FRM) and Time-Dependent Convection (TDC), to study the gamma Dor stars found in the NGC 2506 stellar cluster. The use of both techniques gives us the opportunity of constructing a self-consistent procedure, allowing the mode identification and improving the modelling of the gamma Dor members of the cluster. In this work we present the result of the analysis of the first target of our project, showing the advantadge of modelling cluster member's gamma Dor stars. This is the first step in a more ambitious project. In the near future, we plan to expand the study to other variable members of the NGC 2506 cluster. This will improve our knowledge of gamma Dor pulsators and probe the self-consistency of our procedures.
