Long Period Variables in Local Group Dwarf Galaxies
Long Period Variables in Local Group Dwarf Galaxies
In this work the results are presented of an extensive search for Long Period Variables stars (LPVs) in a sample of Local Group irregular dwarf galaxies. The methods applied for the detection and the extraction of the variable sources are explained. Extensive completeness simulations were carried out to asses the impact on the resulting catalog caused by the observing pattern and algorithms used. The resulting catalog of LPVs was together with color-magnitude diagrams used to draw conclusions on the star-formation history in these galaxies.

Abstract

In this work the results are presented of an extensive search for Long Period Variables stars (LPVs) in a sample of Local Group irregular dwarf galaxies. The methods applied for the detection and the extraction of the variable sources are explained. Extensive completeness simulations were carried out to asses the impact on the resulting catalog caused by the observing pattern and algorithms used. The resulting catalog of LPVs was together with color-magnitude diagrams used to draw conclusions on the star-formation history in these galaxies.
