This catalogue contains results of photometric and spectral observations of eleven Galactic Wolf–Rayet stars of the WN sequence, obtained in 2021–2022 at the Fesenkov...

This catalogue contains results of photometric and spectral observations of seven Galactic Wolf–Rayet stars of the WC and WO sequences, obtained in 2021–2022 at the Fesenkov...

To identify long-period variable (LPV) stars in IC 10-the nearest starburst galaxy of the Local Group-we conducted an optical monitoring survey using the 2.5m Isaac Newton...

Interior models predict that stellar envelopes change from convective to radiative during the pre-main-sequence (pre-MS) evolution of intermediate-mass stars. Although the...

The sub-milliKelvin sensitivity achieved in the Q-band (31-50GHz) line survey of IRC+10216 obtained with the Yebes 40m telescope reveals the presence of several new vibrational...

Radial velocity (RV) curves of Cepheids are essential for studying their pulsation properties and also for measuring their distance via the parallax-of-pulsation method....

The Milky Way (MW) stellar halo, containing debris from past accretion events, serves as a fossil record of hierarchical mass assembly. Due to their distinct properties, RR...

This resource provides the results of a morphological classification of 2,184,283 eclipsing binary candidates from the Gaia DR3 catalogue. The systems are classified into...

The table contains the results of morphological classification of eclipsing binaries and selected parameters from Gaia DR3 (:bibcode: 2023A&A...674A...1G), including...

The table with basic parameters of the observed objects

This service exposes photometric light curves. The light curves are published per-band and are also discoverable through ObsCore.

The table with basic parameters of the observed objects

This service exposes photometric light curves obtained with small telescopes at the Kolonica Observatory. The first published dataset covers observations from 2019–2021. The...

Luminous blue variables (LBVs) exhibit unique variability features, characterized by episodic outbursts (>1mag) accompanied by spectroscopic changes (S Dor variables). It is...

This file contains Galactic stars known or suspected to be variable. It lists all stars that have an entry in the AAVSO International Variable Star Index (VSX;...

In current astronomical surveys with ever-increasing data volumes, automated methods are essential. Objects of known classes from the literature are necessary to train...

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...

AST3-2 is the second of the three Antarctic Survey Telescopes, aimed at wide-field time-domain optical astronomy. It is located at Dome A, Antarctica, which is by many measures...

Age is a stellar parameter that is both fundamental and difficult to determine. Among middle-aged M dwarfs, the most prolific hosts of close-in and detectable exoplanets,...

The properties of the Milky Way's nuclear stellar disc give crucial information on the epoch of bar formation. Mira variables are promising bright candidates to study the...
