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.

The ASAS-SN catalogue of variable stars – IV. Periodic variables in the APOGEE survey [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We explore the synergy between photometric and spectroscopic surveys by searching for periodic variable stars among the targets observed by the Apache Point Observatory Galactic Evolution Experiment (APOGEE) using photometry from the All-Sky Automated ...

On the new late B- and early A-type periodic variable stars [PDF]
Proceedings of the International Astronomical Union, 2013 We summarize the properties of the new periodic, small-amplitude, variable stars recently discovered in the open cluster NGC 3766. They are located in the region of the Hertzsprung-Russell diagram between δ Sct and slowly pulsating B stars, a region ...

Search for variable stars in the young open cluster Stock 18
EPJ 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.

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

Variability of Known Exoplanet Host Stars Observed by TESS
The Astronomical Journal, 2023 Both direct and indirect methods of exoplanet detection rely upon detailed knowledge of the potential host stars. Such stellar characterization allows for accurate extraction of planetary properties, as well as contributing to our overall understanding ...

Random forest automated supervised classification of Hipparcos periodic variable stars [PDF]
, 2011 We present an evaluation of the performance of an automated classification of the Hipparcos periodic variable stars into 26 types. The sub-sample with the most reliable variability types available in the literature is used to train supervised algorithms ...

On Be Star Candidates and Possible Blue Pre-Main Sequence Objects in the Small Magellanic Cloud [PDF]
, 2002 Recently the OGLE experiment has provided accurate light curves and colours for about 2 millions stars in the Small Magellanic Cloud. We have examined this database for its content of Be stars, applying some selection criteria, and we have found a sample

Automated classification of periodic variable stars{Improved methodology for the automated classification of periodic variable stars} [PDF]
, 2011 We present a novel automated methodology to detect and classify periodic variable stars in a large database of photometric time series. The methods are based on multivariate Bayesian statistics and use a multi-stage approach. We applied our method to the
