As mixed with real pulsations, the reflection of super-Nyquist frequencies (SNFs) pose a threat to asteroseismic properties. Although SNFs have been studied in several pulsating...

The Dark Energy Camera (DECam) is a sensitive, wide field instrument mounted at the prime focus of the 4m V. Blanco Telescope in Chile. Beside its main objectives, i.e....

The Bochum Galactic Disk Survey is a project to monitor the stellar content of the Galactic disk in a 6 degree wide stripe centered on the Galactic plane. The data has been...

Extracted sources from the Bochum Galactic Disk Survey. We provide mean photometry in U, B, V, z, r, and i bands. Note that sources in different bands are not matched. Also,...

This service exposes the light curves of stars produced by the Bochum Galactic Disk Survey; several million light curves are provided in the SDSS i and r bands. The lightcurves...

AAVSO Photometric All-Sky Survey (APASS), underway since 2010, covers the entire sky from 7.5 < V < 16.5 magnitude, and in the BVugrizY bandpasses. A northern and a...

The structure and kinematics of the Milky Way disk are largely inferred from the solar vicinity. To gain a comprehensive understanding, it is essential to find reliable tracers...

The Orion Nebula is one of the best-studied star-forming regions in our Galaxy and provides an ideal laboratory to study the early stages of star formation. Understanding the...

Accurate determination of the stellar atmospheric parameters of RR Lyrae stars (RRLs) requires short individual exposures of the spectra to mitigate pulsation effects. We...

We present the first edition of a catalog of variable stars found in the Magellanic Clouds using OGLE-II data obtained during four years: 1997-2000. The catalog covers about 7...

The presence of low-amplitude peaks over the noise in the power spectra of {delta} Sct stars is frequently disregarded. These seemingly insignificant peaks, collectively...

Pioneering photometric, astrometric, and spectroscopic surveys is helping exoplanetary scientists better constrain the fundamental properties of stars within our galaxy and the...

Radial abundance gradients provide sound constraints for chemo-dynamical models of galaxies. Azimuthal variations of abundance ratios are solid diagnostics to understand their...

Periodic variables are always of great scientific interest in astrophysics. Thanks to the rapid advancement of modern large-scale time-domain surveys, the number of reported...

We have performed a critical evaluation of the membership status of all variable stars in globular clusters recorded in the Catalogue of Variable Stars in Globular Clusters...

We explore the characteristics of carbon stars within our Galaxy through a comprehensive analysis of observational data spanning visual and infrared (IR) bands. Leveraging data...

The details of the mass-loss process in the late stages of low- and intermediate-mass stellar evolution are not well understood, in particular its dependence on stellar...

In this Letter we investigate the origin of the Oosterhoff dichotomy in light of recent discoveries related to several ancient merging events of external galaxies with the Milky...

The Baade-Wesselink method, also known as the pulsation parallax method allows us to estimate distances to individual pulsating stars. Accurate geometric parallaxes obtained by...

We present an account of known cataclysmic variables (CVs) that were detected as X-ray sources in eROSITA X-ray surveys and have Gaia DR3 counterparts. We address standard CVs...
