The OmegaWhite survey for short-period variable stars – VII. High amplitude short-period blue variables

Monthly Notices of the Royal Astronomical Society, 2022
ABSTRACTBlue Large-Amplitude Pulsators (BLAPs) are a relatively new class of blue variable stars showing periodic variations in their light curves with periods shorter than a few tens of minutes and amplitudes of more than 10 per cent. We report nine blue variable stars identified in the OmegaWhite survey conducted using ESO’s VST, which shows a ...

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.

Variability of Luminous Stars in the Large Magellanic Cloud Using 10 Years of ASAS Data [PDF]

, 2010
Motivated by the detection of a recent outburst of the massive luminous blue variable LMC-R71, which reached an absolute magnitude M_V = -9.3 mag, we undertook a systematic study of the optical variability of 1268 massive stars in the Large Magellanic ...

Automated Classification of Periodic Variable Stars detected by the Wide-field Infrared Survey Explorer [PDF]

, 2014
We describe a methodology to classify periodic variable stars identified using photometric time-series measurements constructed from the Wide-field Infrared Survey Explorer (WISE) full-mission single-exposure Source Databases.

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.

K2 Variable Catalogue: Variable Stars and Eclipsing Binaries in K2 Campaigns 1 and 0 [PDF]

, 2015
We have created a catalogue of variable stars found from a search of the publicly available K2 mission data from Campaigns 1 and 0. This catalogue provides the identifiers of 8395 variable stars, including 199 candidate eclipsing binaries with periods up

Finding the most variable stars in the Orion Belt with the All Sky Automated Survey [PDF]

, 2010
We look for high-amplitude variable young stars in the open clusters and associations of the Orion Belt. We use public data from the ASAS-3 Photometric V-band Catalogue of the All Sky Automated Survey, infrared photometry from the 2MASS and IRAS ...

Classification of variable stars in the WFCAM Transit Survey

EPJ Web of Conferences, 2013
The WFCAM Transit Survey is a photometric survey in the near-infrared and aims at finding Earth-like planets transiting M-dwarf stars. As a by-product of the survey, a variety of variable stars has been detected.
