Most Rotational Variables Dominated by a Single Bright Feature Are α 2 CVn Stars

The Astronomical Journal, 2023
We previously reported a rare class of variable star light curves isolated from a sample of 4.7 million candidate variables from the ATLAS survey. Dubbed “UCBH” light curves, they have broad minima and narrow, symmetrical maxima, with typical periods of ...

A three-dimensional map of the Milky Way using classical Cepheid variable stars [PDF]

Science, 2018
Cepheids help to map the Galaxy Cepheid variable stars pulsate, which allows their distances to be determined from the periodic variations in brightness. Skowron et al. constructed a catalog of thousands of Cepheids covering a large fraction of the Milky

The ASAS-SN catalogue of variable stars I: The Serendipitous Survey [PDF]

, 2018
The All-Sky Automated Survey for Supernovae (ASAS-SN) is the first optical survey to routinely monitor the whole sky with a cadence of $\sim2-3$ days down to V$\lesssim17$ mag.

The ASAS-SN catalogue of variable stars III: variables in the southern TESS continuous viewing zone [PDF]

Monthly notices of the Royal Astronomical Society, 2018
The All-Sky Automated Survey for Supernovae (ASAS-SN) provides long baseline (${\sim}4$ yrs) light curves for sources brighter than V$\lesssim17$ mag across the whole sky.

Future of the General Catalogue of Variable Stars from the Experience of Recent Name-lists

Open Astronomy, 2021
We briefly outline the history of the General Catalogue of Variable Stars (GCVS) and the New Catalogue of Suspected Variable Stars (NSV catalogue). Recently, we have completed a revision of the NSV catalogue.

The ASAS-SN catalogue of variable stars – V. Variables in the Southern hemisphere [PDF]

Monthly notices of the Royal Astronomical Society, 2019
The All-Sky Automated Survey for Supernovae (ASAS-SN) provides long baseline (∼4 yr) light curves for sources brighter than V ≲ 17 mag across the whole sky.

Wide-field Infrared Survey Explorer (WISE) Catalog of Periodic Variable Stars [PDF]

Astrophysical Journal Supplement Series, 2018
We have compiled the first all-sky mid-infrared variable-star catalog based on Wide-field Infrared Survey Explorer five-year survey data. Requiring more than 100 detections for a given object, 50,282 carefully and robustly selected periodic variables are

THE DETERMINATION OF PERIODS AND THE DEFINITION OF VARIABILITY TYPE OF NEW VARIABLE STAR IRAS 17583+5150

Odessa Astronomical Publications, 2017
The measurements of brightness of the star IRAS 17583+5150 discovered using the Odessa observatory negatives are discussed in the article. The proposed types of these stars are IRAS 17583+5150 -- type SRB (SRC).
