HADS in the Large Magellanic Cloud
Abstract
We present 2323 High-Amplitude δ-Scuti (HADS) candidates discovered in the Large Magellanic Cloud (LMC) by the SuperMACHO survey. Frequency analyses of these candidates reveal that several are multimode pulsators, including 119 whose largest amplitude of pulsation is in the fundamental (F) mode and 19 whose largest amplitude of pulsation is in the first overtone (FO) mode. We discuss properties of these HADS candidates including evidence for an excess of larger amplitude, subluminous candidates.
