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.
