We present a seismic study of the β Cephei star θ Ophiuchi. Our analysis is based on the observation of one radial mode, one rotationally split � = 1 triplet and three components of a rotationally split � = 2 quintuplet for which the m values were well identified by spectroscopy. We identify the radial mode as fundamental, the triplet as p1 and the quintuplet as g1. Our non-local thermodynamic equilibrium abundance analysis results in a metallicity and CNO abundances in full agreement with the…

Constraints on opacities from complex asteroseismology of B-type pulsators: the β Cephei star θ Ophiuchi
We present results of a comprehensive asteroseismic modelling of the β Cephei variable θ Ophiuchi. We call these studies complex asteroseismology because our goal is to reproduce both pulsational

Ground-based observations of the β Cephei CoRoT main target HD 180 642: abundance analysis and mode identification
The known β Cephei star HD 180 642 was observed by the CoRoT satellite in 2007. From the very high-precision light curve, its pulsation frequency spectrum could be derived for the first time
Rotation and convective core overshoot in θ Ophiuchi
Context. Recent work on several β Cephei stars has succeeded in constraining both their interior rotation profile and their convec- tive core overshoot. In particular, a recent study focusing on θ
Modelling of the B-type binaries CW Cephei and U Ophiuchi
Context. Intermediate-mass stars are often overlooked. They are not supernova progenitors, but still host convective cores and complex atmospheres that require computationally expensive treatment.
