dc.description.abstractThis study presents the first detailed analysis of three southern eclipsing binaries. Both – light curves and radial velocity curves – were studied together with their period changes, revealing basic physical and orbital properties of these systems. All three stars, VW Ret, FW Vel, and CW Eri are detached binaries with a few days orbital period. Thanks to our detailed analysis we revealed that all the component stars are slightly heavier than the Sun, laying in the mass range between 1.3 M and 1.6 M . The systems VW Ret, and FW Vel seem to have more dominant secondary components, both in the masses, as well as in luminosities. The system VW Ret is a triple star showing large eclipse times variations with the periodicity of 4 yr. For FW Vel a similar weak variation was also found, but with much lower amplitude of about 56 s only, needed to be independently confirmed. CW Eri shows slightly eccentric orbit (e = 0.015), but only very slow apsidal motion. Moreover, its ages for both component do not agree with each other very well. Hence, it provides a challenge for future more detailed modeling of this interesting system. © 2024 Copernicus Foundation for Polish Astronomy. All rights reserved.
