Bulge Delta Scuti Stars in the MACHO database

, 1997
The authors describe the search for {delta} Scuti stars in the MACHO database of bulge fields. Concentrating on a sample of high amplitude {delta} Scutis, they examine the light curves and pulsation modes. They also discuss their spatial distribution and

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

{\delta} 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 ...

Stellar Variability and Distance Indicators in the Near-infrared in Nearby Galaxies. II. Pulsating Stars in the Carina Dwarf Spheroidal

The Astronomical Journal
We present homogeneous, near-infrared ( JHK _s bands) time-series observations of the classical Carina dwarf spheroidal (dSph) galaxy to determine accurate and precise distances using the pulsating stars as standard candles.

A Search for High-frequency Oscillations in TESS Cycle 7

The Astrophysical Journal Supplement Series
High-quality, short-cadence photometry from TESS enables the detection of rapid oscillators with unprecedented sensitivity. In this work, we conduct a homogeneous search for high-frequency variability using 20 s cadence light curves from TESS Cycle 7 ...

Establishing Baselines for Six Short-period δ Scuti Variables

The Astronomical Journal
As part of our variable star follow-up program, we have examined a number of stars from the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey. Using a combination of our own data, ATLAS data, and other archival data, we confirmed the published

Short-period Variables in TESS Full-frame Image Light Curves Identified via Convolutional Neural Networks

The Astronomical Journal
The Transiting Exoplanet Survey Satellite (TESS) mission measured light from stars in ∼85% of the sky throughout its 2 yr primary mission, resulting in millions of TESS 30-minute-cadence light curves to analyze in the search for transiting exoplanets. To
