Pulsating Stars in the OGLE-III Galactic Disk Fields

We report the identification of various pulsating variables, such as Classical Cepheids (20 objects, light curves below), RR Lyr type stars (45 objects), Long-Period Variables (31 objects), very likely δ Sct type stars (58 objects), and one pulsating white dwarf. The sample also includes candidates for Type II Cepheids and numerous unclassified short-period pulsating stars, which are either of δ Sct or β Cep type.

Based on asteroseismic models constructed for multi-mode δ Sct type pulsators, we estimated distances and physical parameters for some of the stars.

For the purposes of future studies on the spiral structure and star formation history of the Milky Way, we compile data on known Galactic Classical Cepheids.

Details on the newly detected objects and the list of known Galactic Classical Cepheids are available to the astronomical community from the the OGLE Internet archive.
