Revisiting Variable Stars Near Globular Clusters South of −29° Declination
Astronomische Nachrichten, Volume 346, Issue 2, February 2025.ABSTRACT We review an often‐cited but seldom‐accessed catalogue by Fourcade and Laborde (1966) of 785 variable stars near 47 southern Galactic globular clusters, and recover the locations of 85 stars that were not incorporated into subsequent variable star catalogues and hence have become “lost” to the literature.

Search for the Blazhko Effect in Field RR Lyrae Stars Using LINEAR and ZTF Light Curves
The Astronomical JournalWe analyzed the incidence and properties of RR Lyrae stars that show evidence for amplitude and phase modulation (the so-called Blazhko Effect) in a sample of ∼3000 stars with LINEAR and ZTF light curve data collected during the periods of 2002–2008 and ...

RADIATIVE TRANSFER EFFECTS ON THE COLORS OF RR LYRAE STARS
Odessa Astronomical Publications, 2017 The methods of Davis and Cox (1980), are applied to a series of models described by Bono and Stellingwerf (1994) to deter-mine the colors of RR Lyrae stars.

Variability in NGC 3201 Giant Stars
The Astronomical Journal, 2023 We present the analysis of 510 light curves in V and I bands of 255 giant stars in the globular cluster NGC 3201. Our aim is to expand the sample of new types of variables reported in a previous study. These variables show a short period ( P _V < 0.6 day)

The Astrophysical Journal, 2023 We present new empirical infrared period–luminosity–metallicity (PLZ) and period–Wesenheit–metallicity (PWZ) relations for RR Lyae based on the latest Gaia Early Data Release 3 (EDR3) parallaxes.

A Pilot Study to Verify the RR Lyrae Candidates with Vera C. Rubin Observatory Early Alerts
The Astronomical JournalWe present a pilot study using the Vera C. Rubin Observatory early alerts to verify RR Lyrae candidates in the Pan-STARRS1, the Dark Energy Survey, and the Next-Generation Virgo Cluster Survey RR Lyrae catalogs. RR Lyrae candidates fainter than 16 mag in

Search of Short-Period Pulsating Variables(I) [PDF]
Journal of Astronomy and Space Sciences, 1996 CCD differential photometry was carried out for seven stars in the "New Catalogue of Suspected Variable Stars" in order to discover new short-period pulsating variables such as low and high amplitude δ Scuti stars and RR Lyrae stars.

Highlights on eclipsing binary variables from Araucaria Project
EPJ Web of Conferences, 2015 The Araucaria Project, which main goal is to provide precise determination of the cosmic distance scale, has recently made a set of discoveries involving variable stars in binary systems. Among these discoveries we highlight three: 1% precise measurement

Photometric Metallicity and Distance Estimates for ∼136,000 RR Lyrae Stars from Gaia Data Release 3
The Astrophysical Journal, 2023 We present a sample of 135,873 RR Lyrae stars (RRLs) with precise photometric metallicity and distance estimates from our newly calibrated P – ϕ _31 – R _21 –[Fe/H]/ P – R _21 –[Fe/H] and G -band absolute magnitude–metallicity relations.
