Context. The technique of matching synthetic spectra computed with theoretical stellar atmosphere models to the observations is widely used in deriving fundamental parameters of massive stars. When applied to binaries, however, these models generally neglect the interaction effects present in these systems. Aims. The aim of this paper is to explore the uncertainties in binary stellar parameter s that are derived from single-star models. Methods. Synthetic spectra that include the tidal… 
Apsidal motion in the massive binary HD 152218
Massive binary systems are important laboratories in which to probe the properties of massive stars and stellar physics in general. In this context, we analysed optical spectroscopy and photometry of
Alpha Virginis: line-profile variations and orbital elements
Abridged: Alpha Virginis is a binary system whose proximity and brightness allow detailed investigations of the internal structure and evolution of stars undergoing time-variable tidal interactions.
Spectroscopic patch model for massive stars using PHOEBE II and FASTWIND
Context. Massive stars play an important role in the mechanical and chemical evolution of galaxies. Understanding the internal processes of these stars is vital to our understanding of their
The polarization of the binary system Spica, and the reflection of light from stars
Close binary systems often show linear polarization varying over the binary period, usually attributed to light scattered from electrons in circumstellar clouds. One of the brightest close binary
Short-term spectroscopic variability of Plaskett’s star
Context. Plaskett’s star (HD 47129) is a very massive O-star binary in a post Roche-lobe overflow stage. CoRoT observations of this system revealed photometric variability with a number of
A COORDINATED X-RAY AND OPTICAL CAMPAIGN OF THE NEAREST MASSIVE ECLIPSING BINARY, δ ORIONIS Aa. III. ANALYSIS OF OPTICAL PHOTOMETRIC (MOST) AND SPECTROSCOPIC (GROUND-BASED) VARIATIONS
We report on both high-precision photometry from the Microvariability and Oscillations of Stars (MOST) space telescope and ground-based spectroscopy of the triple system δ Ori A, consisting of a
Polarized reflected light from the Spica binary system
Close binary systems often show linear polarization varying over the binary period, usually attributed to light scattered from electrons in circumstellar clouds1–3. One of the brightest close binary
On X-ray pulsations in beta Cephei-type variables
Beta Cephei-type variables are early B-type stars that are characterized by oscillations observable in their optical light curves. At least one Beta Cep-variable also shows periodic variability in
Stellar modelling of Spica, a high-mass spectroscopic binary with a β Cep variable primary component
Binary stars provide a valuable test of stellar structure and evolution, because the masses of the individual stellar components can be derived with h

Spectral modelling of massive binary systems
Context. The spectra of massive binaries may be affected by interactions between the stars in the system. These are believed to produce observational phenomena such as the Struve-Sahade effect. Aims.
Spectral modelling of circular massive binary systems - Towards an understanding of the Struve-Sahade effect?
Context. Some secondary effects are known to introduce variations in spectra of massive binaries. These phenomena, such as the Struve-Sahade effect and the difficulties in determining properly the
