The Optical Gravitational Lensing Experiment. The OGLE-III Catalog of Variable Stars. VI. Delta Scuti Stars in the Large Magellanic Cloud

摘要

The sixth part of the OGLE-III catalog of Variable Stars presents \delta Sctpulsators in the Large Magellanic Cloud. Altogether 2786 variable stars werefound and amongst them 92 are multi-mode objects, including 67 stars pulsatingin the fundamental mode and the first overtone (F/1O), nine double-modepulsators with various combinations of the first three overtones excited(1O/2O, 2O/3O and 1O/3O pulsators), and two triple mode (F/1O/2O) \delta Sctstars. In total 1490 of stars are marked as uncertain, due to scatteredphotometry and small amplitudes. For single-mode objects it was not possible tounambiguously identify pulsation mode, however we suggest the most of thesingle-mode variable stars pulsate in the first overtone.
