A Search of Periodic Variable Stars in the LMC by JWST Photometry

open access: yesThe Astrophysical Journal Supplement Series
Based on high-resolution near-infrared photometric data from the James Webb Space Telescope (JWST) targeting the Large Magellanic Cloud, this study attempts to evaluate the feasibility and sensitivity limits of variable star detection in crowded stellar ...

The MACHO Project Sample of Galactic Bulge High-Amplitude Scuti Stars: Pulsation Behavior and Stellar Properties [PDF]

open access: yes, 1999
We have detected 90 objects with periods and lightcurve structure similar to those of field {delta} Scuti stars, using the Massive Compact Halo Object (MACHO) Project database of Galactic bulge photometry.

MONS and high-amplitude

open access: yes, 2007
The important role of high-amplitude ffi Scuti stars (HADS) in asteroseismological tests of model structure and excitation/damping mechanisms of ffi Scuti variables is emphasized. It is suggested that one or two well--studied HADS, e.g. AI Vel and SX Phe

A New Catalog of 100,000 Variable \emph{TESS} A-F Stars Reveals a Correlation Between $δ$ Scuti Pulsator Fraction and Stellar Rotation

open access: yes
δ Scuti variables are found at the intersection of the classical instability strip and the main sequence on the Hertzsprung-Russell diagram. With space-based photometry providing millions of light-curves of A-F type stars, we can now probe the occurrence rate of δ Scuti pulsations in detail.

The Magnetic delta Scuti Star beta Cas

open access: yes, 2019
We study the pulsational, atmospheric, and magnetic properties of the evolved delta Scuti star beta Cas using a combination of multiple seasons of BRITE-Constellation and SMEI space photometry and multiple-epoch spectropolarimetric observations conducted

The MACHO project sample of galactic bulge high-amplitude δ Scuti stars

open access: yes, 2000
We have detected 90 objects with periods and light-curve structures similar to those of held delta Scuti stars using the Massive Compact Halo Object (MACHO) Project database of Galactic bulge photometry.
