The OGLE-III Catalog of Variable Stars

VI. δ Scuti Stars in the Large Magellanic Cloud

The sixth part of the OGLE-III Catalog of Variable Stars comprises of 2786 δ Scuti (DSCT) stars in the Large Magellanic Cloud (LMC). For all objects we publish the VI multi-epoch OGLE photometry as well as finding charts and basic parameters. Altogheter 1490 of our variables are marked as uncertain, due to scattered photometry and small amplitudes.

Sample light-curves of δ Scuti stars.

The catalog contains 92 multi-mode pulsators including 67 stars pulsating in the fundamental mode and the first overtone (F/1O), nine double-mode pulsators with various combinations of the first three overtones excited (1O/2O, 2O/3O and 1O/3O pulsators), and two triple mode (F/1O/2O) δ Scuti stars. For single-mode objects it was not possible to unambiguously identify pulsation mode, however we suggest the most of the single-mode variable stars pulsate in the first overtone.

The OGLE-III Catalog of δ Scuti stars in the LMC is available from the OGLE Internet archive. See README file there for details.
