A Catalog of New Slowly Pulsating B-type Stars
The Astrophysical Journal Supplement Series, 2023 This paper reports the discovery of new slowly pulsating B-type stars. Based on the photometric, spectral, and astrometric data of the TESS, LAMOST, and Gaia surveys, we have found 286 new slowly pulsating B-type (SPB) stars and 21 candidates.

The pulsating variable star population in DDO210 [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 We have probed the pulsating variable star content of the isolated Local Group dwarf galaxy, DDO210 (Aquarius), using archival Advanced Camera for Surveys/$Hubble$ $Space$ $Telescope$ imaging in the F475W and F814W passbands. We find a total of 32 RR Lyrae stars (24 ab-type, 8 c-type) and 75 Cepheid variables. The mean periods of the ab-type and c-type

Variability and pulsations in the Be star 66 Ophiuchi [PDF]
Astronomy & Astrophysics, 2002 Oph is a Be star seen under a moderate inclination angle that shows strong variability from UV to IR wavelengths. A concise review of long-term variability history is given. High resolution, high S /N spectroscopic observations obtained in 1997, 1998 and 2001 and spectropolarimetric observations obtained in 2000 are presented.

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.

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.
