We present 2323 high-amplitude δ-Scuti (HADS) candidates discovered in the Large Magellanic Cloud by the SuperMACHO survey (Rest et al.). 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. Using Fourier decomposition of the HADS light curves, we find that the period-luminosity (PL) relation defined by…

We have examined the period-luminosity (P-L) relation for delta Scuti stars using Gaia DR2 parallaxes. We included 228 stars from the catalogue of Rodriguez et al. (2000), as well as 1124 stars
A Pulsation Review of Delta Scuti and Related Stars
The $$\delta$$ Sct stars are by far the most common type of pulsating stars at spectral type A. In this, the most extensive review of $$\delta$$ Sct stars in the Kepler era, the following topics
