The following Table 1 lists 508 timings of minima of eclipsing binaries secured both by photoelectric as well as by visual means by BBSAG observers, primarily obtained between...

High-dispersion spectrograms of the interacting close binary TX UMa taken in 1969-73 around the primary minima were used to display the rotational effect of the mass gaining...

Our multicolour photometric measurements of V361 Cam (P=8.64day, V=10.79mag, e=0.12, B5 V + B9 V) over the past 16 years, as well as TESS data, allowed us to determine for the...

New high-precision photometric measurements of the eclipsing star V839 Cep (P=9.96-day, V(A+B)=9.64mag, e=0.07, B6 V + B7 V), which is the A component of the visual double star...

The absolute proper motions for a total of 92 globular clusters of the Milky Way (60% of all clusters included in the catalogue published by Harris, 1996, Cat. VII/195) are...

This catalogue contains compilations of observable data for 176 massive close binaries with components earlier than approximately B5 of the main sequence are presented. Cone...

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

Observations of low-mass stars have frequently shown a disagreement between observed stellar radii and radii predicted by theoretical stellar structure models. This "`radius...

Precise measurements of stellar parameters are required in order to develop our theoretical understanding of stellar structure. These measurements enable errors and...

The veracity of stellar evolution models and theoretical internal structure constants may be subjected to stringent tests by using physical parameters obtained from...

Eclipsing binaries are important benchmark objects to test and calibrate stellar structure and evolution models. This is especially true for binaries with a fully convective...

EBLM J0113+31 is a moderately bright (V=10.1), metal-poor ([Fe/H]~-0.3) G0V star with a much fainter M dwarf companion on a wide, eccentric orbit (=14.3d). We have used...

We present a comprehensive census of X-ray millisecond pulsars (MSPs) in 29 Galactic globular clusters (GCs), including 68 MSPs with confirmed X-ray luminosities and 107 MSPs...

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

We present a detailed study of the stellar and orbital parameters of the post-common envelope binary central star of the planetary nebula Ou5. Low-resolution spectra obtained...

We present VIVACE, the VIrac VAriable Classification Ensemble, a catalogue of variable stars extracted from an automated classification pipeline for the Vista Variables in the...

The accuracy of theoretical mass, radius and effective temperature values for M-dwarf stars is an active topic of debate. Differences between observed and theoretical values...
