Variability survey in the young open cluster IC 1805

TL;DR

This study conducts a variability survey of the young open cluster IC 1805 to identify early-type pulsating stars like beta Cephei and SPB, aiding asteroseismology research.

Contribution

It provides new observational data on variable stars in IC 1805, supporting ensemble asteroseismology of young open clusters.

Findings

Identification of candidate pulsating stars

Enhanced understanding of stellar variability in IC 1805

Foundation for future asteroseismic studies

Abstract

The variability survey in the young open cluster IC 1805 is a part of the ongoing program of searching for early-type variable stars in open clusters of the northern sky conducted in Wroclaw (see Jerzykiewicz et al. 2011 and references therein). We are particularly interested in pulsating stars such as beta Cephei and SPB. These stars are very promising targets for asteroseismology. In particular, open clusters rich in these variables can be used for so called ensemble asteroseismology (Saesen et al. 2010).
