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.

A Classification Catalog of Periodic Variable Stars for LAMOST DR9 Based on Machine Learning

open access: yesThe Astrophysical Journal Supplement Series
Identifying and classifying variable stars is essential to time-domain astronomy. The Large Area Multi-Object Fiber Optic Spectroscopic Telescope (LAMOST) acquired a large amount of spectral data.

Search for variable stars in the young open cluster Stock 18 [PDF]

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.

Searching for Anomalies in the ZTF Catalog of Periodic Variable Stars

open access: yes, 2021
Periodic variables illuminate the physical processes of stars throughout their lifetime. Wide-field surveys continue to increase our discovery rates of periodic variable stars.

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.

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
