Classification of Periodic Variable Stars from TESS
Astrophysical Journal, Supplement SeriesThe number of known periodic variable stars has increased rapidly in recent years. As an all-sky transit survey, the Transiting Exoplanet Survey Satellite (TESS) plays an important role in detecting low-amplitude variable stars.

Variability Catalog of Stars Observed during the TESS Prime Mission
The Astrophysical Journal Supplement Series, 2023 During its 2 yr Prime Mission, TESS observed over 232,000 stars at a 2 minute cadence across ∼70% of the sky. These data provide a record of photometric variability across a range of astrophysically interesting timescales, probing stellar rotation ...

Sparse Logistic Regression for RR Lyrae versus Binaries Classification
The Astrophysical Journal, 2023 RR Lyrae (RRL) stars are old, low-mass, radially pulsating variable stars in their core helium burning phase. They are popular stellar tracers and primary distance indicators since they obey well-defined period–luminosity relations in the near-infrared ...

Multifilter Time-series Observations of Eleven Blue Short-period ATLAS Variable Stars
The Astronomical Journal, 2023 Eleven periodic variable stars were observed photometrically through two to four filters from the set UBVR _C I _C . Phase-folded data for each star cover full cycles of variation.

Asteroseismic Study of KUV03442+0719 with Parallax Constraints
The Astrophysical Journal, 2023 Hydrogen atmosphere white dwarf KUV03442+0719 was first reported as a pulsator by Gianninas et al. in 2006. Follow-up campaigns by Su et al. revealed more periods.
