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...

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...
