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.

The impact of large-scale, long-term optical surveys on pulsating star research
EPJ Web of Conferences, 2017 The era of large-scale photometric variability surveys began a quarter of a century ago, when three microlensing projects - EROS, MACHO, and OGLE - started their operation.

A unifying explanation of complex frequency spectra of gamma Dor, SPB and Be stars: combination frequencies and highly non-sinusoidal light curves [PDF]
, 2015 There are many Slowly Pulsating B (SPB) stars and γ Dor stars in the Kepler mission data set. The light curves of these pulsating stars have been classified phenomenologically into stars with symmetric light curves and with asymmetric light curves.

Discovery of magnetic fields in three He variable Bp stars with He and Si spots [PDF]
, 2006 It is essential for the understanding of stellar structure models of high mass stars to explain why constant stars, non-pulsating chemically peculiar hot Bp stars and pulsating stars co-exist in the slowly pulsating B stars and beta Cephei instability ...

Periodic variable A-F spectral type stars in the southern TESS continuous viewing zone. I. Identification and classification [PDF]
Astronomy & AstrophysicsOur primary objective is to accurately identify and classify the variability of A-F stars in the southern continuous viewing zone of the TESS satellite. The brightness limit was set to 10\,mag to ensure the utmost reliability of our results and allow for

Uncorrelated Amplitude and Frequency Variations of the Harmonics in SX Phoenicis Star XX Cygni
The Astronomical Journal, 2023 Harmonics are quite common in pulsating stars. They are always considered to mimic the behaviors of their independent parent pulsation modes, and are not taken for key information in asteroseismology.
