This bibliographic catalogue lists radii of line emitting regions around more than 100 Be stars determined from high signal to noise registrations of emission line profiles,...

There is growing evidence that M-dwarf stars suffer radius inflation when compared to theoretical models, suggesting that models are missing some key physics required to...

Detached eclipsing binary star systems are our primary source of measured physical properties of normal stars. I introduce DEBCat: a catalog of detached eclipsing binaries with...

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 given catalogue is a revised version of the catalogue (Zakhozhaj, 1987). The previous numeration is preserved, and the stars, with trigonometric, photometric and spectral...

Based on dense series of photoelectric observations and on our radial-velocity measurements, the radii of 62 northern Cepheids are calculated by Balona's method. For each star...

We performed photometric, spectroscopic and orbital period investigations of ASASSN-V J015428.67+204247.2 (hereafter, J015428) for the first time. The light curves of VRI bands...

We wrote and used an automated flare detection Python script to search for super-flares on main sequence stars of types A, F, G, K and M in Kepler's long-cadence data from Q0 to...

The most accurate stellar astrophysical parameters were collected from the solutions of the light and the radial velocity curves of 257 detached double-lined eclipsing binaries...

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...

Based on the spectral observations of the LAMOST (DR2) survey, the radii, masses, and luminosities of 700480 stars were estimated. These stars belong to spectral types A, F, G,...

This article presents and discusses a critical compilation of accurate, fundamental determinations of stellar masses and radii. We have identified 95 detached binary systems...

Transit observations have found the majority of exoplanets to date. Also spectroscopic observations of transits and eclipses are the most commonly used tool to characterize...

We present a publicly available library of model atmospheres with radiative-convective equilibrium pressure-temperature (P-T) profiles fully consistent with equilibrium chemical...

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....

High-precision space-based photometry obtained by the Kepler and TESS missions has revealed evidence of rotational modulation associated with main-sequence (MS) A- and late...

In this work, we present the analysis of 976814 FGKM dwarf and subgiant stars in the Transiting Exoplanet Survey Telescope (TESS) full frame images (FFIs) of the Southern...

We report the detection of a transiting, dense Neptune planet candidate orbiting the bright (V=8.6) K0.5V star HD 95338. Detection of the 55-d periodic signal comes from the...

Nearby detached double-lined eclipsing binaries with most accurate data were studied and 290 systems were found with at least one main-sequence component having a metallicity of...

We report on the detection of pulsations of three pulsating subdwarf B stars observed by the Transiting Exoplanet Survey Satellite (TESS) satellite and our results of mode...
