Analyses of very accurate CoRoT space photometry, past Johnson V photoelectric photometry and high-resolution echelle spectra led to the determination of improved and consistent fundamental stellar properties of both components of AU Monocerotis. We derived new, accurate ephemerides for both the orbital motion (with a period of 11 d . 113) and the long-term, overall brightness variation (with a period of 416 d .9) of this strongly interacting Be + G semi-detached binary. It is shown that this… 
HD 63021: Chromospheric Activity and Mass Transfer in a Close Binary
Prompted by X-ray detections from multiple surveys, we investigated the A-type star HD 63021 and found that it is a double-lined spectroscopic binary with highly variable emission associated with the
Reconstruction of an Accretion Disk Image in AU Mon from CoRoT Photometry
Abstract The long-period binary system AU Mon was photometrically observed on-board the CoRoT satellite in a continuous run of almost 60 days long which has covered almost 5 complete cycles.
V346 Centauri: Early-type eclipsing binary with apsidal motion and abrupt change of orbital period
New physical elements of the early B-type eclipsing binary V346 Cen are derived using the HARPS spectra downloaded from the ESO archive and also numerous photometric observations from various
Fundamental stellar and accretion disc parameters of the eclipsing binary DQ Velorum
Context. To add to the growing collection of well-studied double periodic variables (DPVs) we have carried out the first spectroscopic and photometric analysis of the eclipsing binary DQ Velorum to
The evolution stage and massive disc of the interacting binary V 393 Scorpii
V 393 Scorpii is a bright Galactic Double Periodic Variable showing a long photometric cycle of ≈253 d. We present new VIJK photometric time series for V 393 Scorpii along with the analysis of All
Modeling the Accretion Structure of AU Mon
AU Mon is a long-period (11.113 days) Algol-type binary system with a persistent accretion disk that is apparent as double-peaked Hα emission. We present previously unpublished optical spectra of AU
Properties and nature of Be stars 30. Reliable physical properties of a semi-detached B9.5e+G8III binary BR CMi = HD 61273 compared to those of other well studied semi-detached emission-line binaries
Reliable determination of the basic physical properties of hot emission-line binaries with Roche-lobe filling secondaries is important for developing the theory of mass exchange in binaries. It is a
