This catalogue contains information about 44 binaries with known photometric orbit elements and unknown spectroscopic one. Cone search capability for table V/118/catalog (Catalog)

The catalog contains two parts: 96 well known semidetached eclipsing binaries with known photometric and spectroscopic orbits (table1.dat), and 136 semidetached eclipsing...

Based on positional observations, we have determined the orbits of 130 visual double stars for the first time and improved the orbits of 321 stars. The histogram of...

The dynamic stability of 38 observed hierarchical triple stars with known orbital elements of the internal and external binary subsystems and component masses is considered....

Based on the correlation radial-velocity measurement, we discovered new spectroscopic subsystems in the components of six visual multiple stars and determined the elements of...

The rotation of a star and the revolutions of its planets are not necessarily aligned. This article reviews the measurement techniques, key findings, and theoretical...

Based on positional observations and measurements of radial velocities, the orbits of 850 wide visual double stars have been determined. The parameters of the log-normal...

Being one of the most fundamental physical parameter of astronomical objects, mass plays a vital role in the study of exoplanets, including their temperature structure, chemical...

RR Lyrae stars are one of the primary distance indicators for old stellar populations such as globular clusters, dwarf galaxies and galaxies. Typically, fundamental-mode RR Lyr...

SDSS-V is carrying out a dedicated survey for white dwarfs, single and in binaries, and we report the analysis of the spectroscopy of 504 cataclysmic variables (CVs) and CV...

A key event in the history of the Milky Way is the formation of the bar. This event affects the subsequent structural and dynamical evolution of the entire Galaxy. When the bar...

We use an updated method for the detection of double-lined spectroscopic binaries (SB2s) using vsini values from spectral fits. The method is applied to all spectra from Large...

Eccentricity of wide binaries is difficult to measure due to their long orbital periods. With Gaia's high-precision astrometric measurements, eccentricity of a wide binary can...

Young exoplanets and their corresponding host stars are fascinating laboratories for constraining the time-scale of planetary evolution and planet-star interactions. However,...

Holczer, Mazeh, and collaborators (Holczer et al. 2016ApJS..225....9H, Cat. J/ApJS/225/9) used the Kepler 4-yr observations to derive a transit-timing catalog, identifying 260...

The time-series component of Wide-field Infrared Survey Explorer (WISE) is a valuable resource for the study of variable objects. We present an analysis of an all-sky sample of...

We present 126 eclipsing binary candidates among 4683 Catalina Sky Surveys (CSS) detached and semi-detached eclipsing binary systems (EBs) showing cyclic or quadratic period...

The discovery and characterization of Algol eclipsing binaries (EAs) provide an opportunity to contribute for a better picture of the structure and evolution of low-mass stars....

We report on H-band spectra of chemically peculiar Mercury-Manganese (HgMn) stars obtained via the SDSS/APOGEE survey. As opposed to other varieties of chemically peculiar stars...

Twin binaries were identified among the eclipsing binaries with {delta}>-30{deg} listed in the All Sky Automated Survey (ASAS) catalogue. In addition to the known twin...
