We present the analysis of a peculiar W~Virginis (pWVir) type-II Cepheid, OGLE-LMC-T2CEP-211 ($P_{puls}=9.393\,d$), in a double-lined binary system ($P_{orb}=242\,d$), which shed light on virtually unknown evolutionary status and structure of pWVir s

A chemical abundance analysis is made of two F type high proper motion stars selected from the {\sc ELODIE} library. We use high resolution (R=42\,000) and high signal to noise ratio (S/N=103, 36 $-$per$-$pixel) \'echelle spectra from the {\sc ELODIE

In this study, which is based on spectral disentangling in binary systems, ε Lupi (HD 136504) has been studied. ε Lupi is a double-lined spectroscopic binary system (SB2) consisting of two early type B stars. A total of 575 spectra of ε Lupi downl

We combined photometry from the All Sky Automated Survey (ASAS) and the Transiting Exoplanet Survey Satellite (TESS) with high-resolution spectroscopy from the ESO public archive to obtain, for the first time, absolute physical and orbital parameters
