Characterizing the variability of Melotte 111 AV 1224: a new variable star in the Coma Berenices open cluster

Abstract

A search for new pulsating stars in the Coma Berenices open cluster was carried out. As a result of this search the cluster member Melotte 111 AV 1224 presented clear indications of photometric variability. In order to determine its physical parameters Strömgren standard indices and low-resolution spectra were acquired. In this work we present the preliminary results of these observations.
