Aims. We present the results of a detailed analysis of 452 ground-based, high-resolution high S/N spectroscopic measurements spread over 4.5 years for β Canis Majoris with the aim of determining the pulsational characteristics of this star, and then using them to derive seismic constraints on the stellar parameters. Methods. We determined pulsation frequencies in the Si III 4553 A line with Fourier methods. We identified the m-value of the modes by taking the photometric identifications of the…

An asteroseismic study of the β Cephei star 12 Lacertae: multisite spectroscopic observations, mode identification and seismic modelling
We present the results of a spectroscopic multisite campaign for the β Cephei star 12 (DD) Lacertae. Our study is based on more than thousand high-resolution high S/N spectra gathered with eight
An asteroseismic study of the β Cephei star θ Ophiuchi: constraints on global stellar parameters and core overshooting
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
Multisite spectroscopic seismic study of the β Cep star V2052 Ophiuchi: inhibition of mixing by its magnetic field
We used extensive ground-based multisite and archival spectroscopy to derive observational constraints for a seismic modelling of the magnetic β Cep star V2052 Ophiuchi. The line-profile variability
CoRoT high-precision photometry of the B0.5 IV star HD 51756
Context. OB stars are important constituents for the ecology of the Universe, and there are only a few studies on their pulsational properties detailed enough to provide important feedback on current
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
New Beta Cephei Stars from the KELT Project
We present the results of a search for Galactic β Cephei stars, which are massive pulsating stars with both pressure modes and mixed modes. Thus, these stars can serve as benchmarks for seismological
Asteroseismology and interferometry
Current limitations to asteroseismic studies are discussed, including difficulties in mode identification and in the accurate determination of global parameters of pulsating stars, and how interferometric observations may contribute to overcome these limitations are discussed.
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
Asteroseismic observations of OB stars
Abstract The region of the hot end of the main-sequence is hosting pulsating stars of different types and flavours. Pulsations are not only observed for Slowly pulsating B stars (mid to late B-type

Context. Recent progress in the seismic interpretation of field β Cep stars has resulted in improvements of the physics in the stellar structure and evolution models of massive stars. Further


Asteroseismology of the β Cephei star ν Eridani: interpretation and applications of the oscillation spectrum
The oscillation spectrum of v Eri is the richest known for any variable of the β Cephei type. We interpret the spectrum in terms of normal mode excitation and construct seismic models of the star.

Asteroseismology of HD 129929: Core Overshooting and Nonrigid Rotation
High-quality multicolor Geneva photometric data taken over 21 years of the B3Vstar HD 129929 detect six frequencies, among which appear the effects of rotational splitting with a spacing of ∼0.0121 cycles per day, which implies that the star rotates very slowly.
