We reconsidered the previous studies of properties of magnetic stars based on the latest data on average surface magnetic fields of 177 stars. New, corrected results have been...

We use the FUV fluxes measured with the GALEX to study the star formation properties of galaxies collected in the Local Orphan Galaxies catalog (LOG, 2011AstBu..66....1K). Among...

The results of a spectral classification of 257 M stars observed in the Cepheus region are given. Their equatorial coordinates, photographic stellar magnitudes, and spectral...

A 10th list of late-type M and C stars found on plates of the First Byurakan Spectral Sky Survey in the -11{deg}<{delta}<-7{deg} belt within area of about 1070{deg}^2^ is...

Due to the high quality of Gaia DR2 stellar parallaxes and proper motions, we can study the Cygnus OB2 region up to G=17.5mag in circular region centred at...

Cataclysmic Variables (CVs) are interacting binaries consisting of at least three components that control their colour and magnitude. Using Gaia we here investigate the...

We report the period, eccentricity, and mass determination for the Transiting Exoplanet Survey Satellite (TESS) single-transit event candidate TOI-222, which displayed a single...

Extremely low-mass white dwarf stars (ELMs) are M<0.3M_{sun} helium-core white dwarfs born either as a result of a common-envelope phase or after a stable Roche lobe overflow...

In this work, we investigate the reason behind the increased occurrence of S0 galaxies in high-density environments. Our sample comprises of ~2500 spiral and ~2000 S0 galaxies...

HI stacking has proven to be a highly effective tool to statistically analyse average HI properties for samples of galaxies which may or may not be directly detected. With the...

We present the catalogue and basic properties of sources in AS2UDS, an 870-{mu}m continuum survey with the Atacama Large Millimetre/sub-millimetre Array (ALMA) of 716...

Identifying active galactic nuclei (AGNs) through their X-ray emission is efficient, but necessarily biased against X-ray-faint objects. We aim to characterize this bias by...

This work extends previous kinematic studies of young stars in the head of the Orion A cloud (OMC-1/2/3/4/5). It is based on large samples of infrared, optical, and X-ray...

We have determined the rate of large accretion events in Class I and II young stellar objects (YSOs) by comparing the all-sky digitized photographic plate surveys provided by...

We present optical photometric, spectroscopic data for the stars in the high Galactic latitude molecular cloud MBM 110. For the complete membership selection of MBM 110, we also...

NGC 6402 is among the most massive globular clusters in the Galaxy, but little is known about its detailed chemical composition. Therefore, we obtained radial velocities and/or...

We present a list of 220 face-on, almost bulgeless galaxies assumed to be counterparts to the objects from the Reference Flat Galaxy Catalogue (RFGC). We selected the Sc-, Scd-,...

We present bolometric light curves constructed from multiwavelength photometry of Type Ia supernovae (SNe Ia) from the Carnegie Supernova Project and the CfA Supernova Group,...

In a shallow near-infrared survey of the dwarf irregular galaxy, NGC3109, near the periphery of the Local Group, we have found eight Mira variables, seven of which appear to be...

We present a study of the integrated properties of the 835 galaxies in the Calar-Alto Legacy Integral Field spectroscopy Area survey. To derive the main physical parameters of...
