The GFCAT: A Catalog of Ultraviolet Variables Observed by GALEX with Subminute Resolution
The Astrophysical Journal Supplement Series, 2023 We have performed the first systematic search of the full Galaxy Evolution Explorer (GALEX) data archive for astrophysical variability on timescales of seconds to minutes by rebinning data across the whole mission to 30 s time resolution.

Eight Phase-step δ Scuti Variables in TESS Data
The Astronomical JournalAnalysis of the previously classified delta Scuti variable star MW Camelopardalis using data from the Transiting Exoplanet Survey Satellite sparked a deeper inquiry due to unexpected patterns within the target’s observed − calculated ( O − C ) diagram ...

Dealing With δ-Scuti Variables: Transit Light Curve Analysis of Planets Orbiting Rapidly Rotating, Seismically Active A/F Stars [PDF]
The Astronomical Journal, 2019 Abstract We measure the bulk system parameters of the seismically active, rapidly rotating δ-Scuti KOI-976 and constrain the orbit geometry of its transiting binary companion using a combined approach of asteroseismology and gravity-darkening light curve analysis. KOI-976 is a 1.62 ± 0.2 M ⊙ star with a measured v sin(i)

Asteroseismology of Triple-mode Radial δ Scuti Star: TIC 400562821
The Astrophysical JournalWe investigated the pulsating behavior of TIC 400562821 using high-precision observations from TESS. Fourier analysis of time-series data revealed three independent frequencies.

A Need to Revise Stellar Opacities from Asteroseismology of δ Scuti Stars
The Astrophysical Journal Letters, 2023 We construct seismic models of the four double-mode radial δ Scuti stars adopting opacities from three databases: OPAL, OP, and OPLIB. The aim is to find the models that fit the observed frequencies of the two radial modes and have the effective ...
