Aims. We have selected 13 double-line eclipsing binary systems (DLEBS), strategically
positioned in the HR diagram, to infer the mass dependence of the core overshooting …

Emission-line stars in young open clusters are identified to study their properties, as a
function of age, spectral type and evolutionary state. 207 open star clusters were observed …

We apply probabilistic generative modelling of colour–magnitude diagrams to six young
Galactic open star clusters and determine their mass functions, binary mass-ratio …

We have summarized all measurements for galactic field stars (1474 objects) from the
literature published over more than two decades. These measurements were, for the first …

Context. Open clusters are a useful tool when investigating several topics connected with
stellar evolution; for example the age or distance can be more accurately determined than …

The chemically peculiar (CP) stars of the upper main sequence are excellent astrophysical
laboratories to test the diffusion, mass-loss, rotational mixing, and pulsation in the (non-) …

We present here the first abundance analysis of 44 late B-, A-, and F-type members of the
young open cluster M6 (NGC 6405, age about 75 Myr). Low-and medium-resolution spectra …

We present the results of the investigation of 58 open clusters using UBVRI CCD photometry
(Johnsons-Cousins system) and Gaia eDR3 data. The membership probability of the stars in …

Context. Poorly-populated star clusters may have photometric and structural properties not
much different from asterisms, to the point that, in some cases, widely-used databases …
