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.

Classification of Periodic Variable Stars from TESS [PDF]

The Astrophysical Journal Supplement Series
The number of known periodic variable stars has increased rapidly in recent years. As an all-sky transit survey, the Transiting Exoplanet Survey Satellite (TESS) plays an important role in detecting low-amplitude variable stars.

Phase-night diagram for periodic variable stars [PDF]

Symposium - International Astronomical Union, 1986
A program has been developed for the Hewlett-Packard Computer 9845 to represent in a graphical form the period of observability, for individual nights, of periodic phenomena of stars with respect to the phase. One version of the program (Fig. 1) gives the observability with respect to the phase for the whole year. The other version (Fig.

A New Period Determination Method for Periodic Variable Stars [PDF]

Publications of the Astronomical Society of the Pacific, 2022
Abstract Variable stars play a key role in understanding the Milky Way and the universe. The era of astronomical big data presents new challenges for quick identification of interesting and important variable stars. Accurately estimating the periods is the most important step to distinguish different types of variable stars.

Periodic Variable Stars Modulated by Time-Varying Parameters [PDF]

The Astrophysical Journal, 2021
Abstract Many astrophysical phenomena are time-varying, in the sense that their brightness changes over time. In the case of periodic stars, previous approaches assumed that changes in period, amplitude, and phase are well described by either parametric or piecewise-constant functions.

Characterization of CoRoT target fields with BEST: Identification of periodic variable stars in the IR01 field [PDF]

, 2007
We report on observations of the CoRoT IR01 field with the Berlin Exoplanet Search Telescope (BEST). BEST is a small aperture telescope with a wide field of view (FOV).

New periodic variable stars coincident with ROSAT sources discovered using SuperWASP [PDF]

, 2007
We present optical lightcurves of 428 periodic variable stars coincident with ROSAT X-ray sources, detected using the first run of the SuperWASP photometric survey. Only 68 of these were previously recognised as periodic variables.

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

The 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.
