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 ...

“Inter-Longitude Astronomy” project: long period variable stars [PDF]
Advances in Astronomy and Space Physics, 2014 This article contains the highlights of complex studies of long-period variable stars such as Miras: semiregular, symbiotic (particularly, pulsating symbiotic), as well as RV Tauri-type stars. In the course of these studies, important characteristics of mean light curves were determined.

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

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 ...

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 ...
