Classification of variable stars in the WFCAM Transit Survey

open access: yesEPJ 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.

Detecting Short Period Variable Stars with Gaia [PDF]

open access: yesAIP Conference Proceedings, 2009
We analyzed the frequency domain of time series of simulated ZZ Ceti light-curves to investigate the detectability and period recovery performance of short period variables (periods < 2 hours) for the Gaia mission. In our analysis, first we used a non-linear ZZ Ceti light-curves simulator code to simulate the variability of ZZ Ceti stars (we assumed

Short-period variability in Be stars [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1990
Summary A highly significant correlation is found between the projected rotational velocities and the photometric periods of Be stars. We show that this correlation may be readily understood if the photometric period is equated with the rotational period.

Search for variable stars in the young open cluster Stock 18

open access: yesEPJ Web of Conferences, 2017
We have carried out multi-epoch deep I band photometry of the open cluster Stock 18 to search for variable stars in star forming regions. In the present study, we report identification of 28 periodic and 165 non-periodic variables stars.

The Periods of Cataclysmic Variable Stars [PDF]

open access: yesInternational Astronomical Union Colloquium, 1983
To understand the structure and evolution of the cataclysmic variables, we will need accurate values for their masses, dimensions, mass transfer rates, and other physical properties. Unfortunately, despite an abundance of observational data on these systems, there is a severe dearth of reliable, quantitative information about their fundamental physical

A Population of Dipper Stars from the Transiting Exoplanet Survey Satellite Mission

open access: yesThe Astrophysical Journal Supplement Series, 2022
Dipper stars are a classification of young stellar objects that exhibit dimming variability in their light curves, dropping in brightness by 10%–50%, likely induced by occultations due to circumstellar disk material.
