We studied the properties of star formation and the characteristics of young stars in a quiet region located beyond the outskirts of the prominent star-forming cluster NGC 346...

Pressure-mode frequencies in {delta} Scuti stars may exceed the Nyquist limit of Kepler long-cadence photometry and appear as reflected Nyquist aliases at lower frequencies. We...

The origin of the highly ionized iron emission (FeXXV at 6.7keV) characterizing the Galactic ridge X-ray emission (GRXE) remains a fundamental puzzle in high-energy...

This table is a unified catalogue of objects from the OGLE Collection of Variable Stars (OCVS) (https://www.astrouw.edu.pl/ogle/ogle4/OCVS). It was constructed by merging...

We combine photometric metallicities with astrometry from Gaia DR3 to examine the chemodynamic structure of ~250000 K dwarfs in the solar neighbourhood (SN). In kinematics, we...

The Survey for Distant Solar Twins aims to find stars very similar to the Sun at distances of 1-4kpc, several times more distant than any currently known solar twins and...

The observed properties of galaxies are strongly dependent on both their total stellar mass and their morphology. Furthermore, the environment is known to play a strong role in...

We present a homogeneous analysis of all DA stars labelled as magnetic in the Montreal White Dwarf Database. Our sample is restricted to almost all known magnetic white dwarf...

Globular clusters have been widely studied in terms of light element variations present in their different stellar populations. However, the nature of the polluter(s)...

Our survey of the fourth Fermi Large Area Telescope catalog (4FGL) unassociated gamma-ray source regions using the X-Ray Telescope (XRT) and Ultraviolet/Optical Telescope (UVOT)...

Hot subdwarf stars, located at the end of the blue horizontal branch, have a burning helium core, and are crucial for studying stellar structure. Currently, the number of known...

Stellar systems consisting of three or more stars are not an uncommon occurrence in the Galaxy. Nearly 50% of solar-type wide binaries with separations >1000AU are actually...

In this paper, we present photometric observations and period analysis of two totally eclipsing binaries with extremely low-amplitude light curves. Both binaries exhibit typical...

The identification of physically associated kiloparsec-scale quasar pairs is important for understanding galaxy evolution, the growth of supermassive black holes, and the...

Spectra from surveys hosted by Data Central. Most spectra were taken with the multi-object spectroscopy facilities 2dF (Anglo-Australian Telescope) and 6dF (UK Schmidt Telescope).

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

This service exposes photometric light curves of eclipsing binaries from Gaia DR3 epoch photometry via the VO SSA protocol. The light curves are published per-band and are also...

We present the discovery of TIC-65910228 b / NGTS-38 b, a giant exoplanet with a radius of 1.081+/-0.047 RJ and a mass of 4.78^+0.39^_-0.37_MJ on a long period...

We present the kinematic analysis of 246 stars within 4' from the center of Orion Nebula Cluster (ONC), the closest massive star cluster with active star formation across the...

We present high-cadence ultraviolet through near-infrared observations of the Type Ia supernova (SN Ia) 2023bee at D=32+/-3Mpc, finding excess flux in the first days after...
