Aims. Using the CoRoT space based photometry of the O-type binary HD 46149, stellar atmospheric effects related to rotation can be separated from pulsations, because they leave distinct signatures in the light curve. This offers the possibility of characterising and exploiting any pulsations seismologically. Methods. Combining high-quality space based photometry, multi-wavelength photometry, spectroscopy and constraints imposed by binarity and cluster membership, the detected pulsations in HD… 
Variability in the CoRoT photometry of three hot O-type stars HD 46223, HD 46150, and HD 46966
Context. The detection of pulsational frequencies in stellar photometry is required as input for asteroseismological modelling. The second short run (SRa02) of the CoRoT mission has provided
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
An asteroseismic study of the O9V star HD 46202 from CoRoT space-based photometry
The O9V star HD46202, which is a member of the young open cluster NGC 2244, was observed by the CoRoT satellite in October/November 2008 during a short run of 34 days. From the very high-precision
Gravito-inertial and pressure modes detected in the B3 IV CoRoT target HD 43317
Context. OB stars are important building blocks of the Universe, but we have only a limited sample of them well understood enough from an asteroseismological point of view to provide feedback on the
MOST detects corotating bright spots on the mid-O-type giant ξ Persei
We have used the MOST (Microvariability and Oscillations of STars) microsatellite to obtain four weeks of contiguous high-precision broad-band visual photometry of the O7.5III(n)((f)) star ξ Persei

Context. We present modelling of the β Cep star HD 180642 based on its observational properties deduced from CoRoT and ground-based photometry as well as from time-resolved spectroscopy. Aims. We
Red noise and pulsations in evolved massive stars
We examine high-cadence space photometry taken by the Transiting Exoplanet Survey Satellite (TESS) of a sample of evolved massive stars: 26 Wolf–Rayet stars (WRs) and eight luminous blue variables
Radial dependence of line profile variability in seven O9–B0.5 stars
Context. Massive stars show a variety of spectral variabilities: discrete absorption components in UV P-Cygni profiles. optical line profile variability, X-ray variability, and radial velocity

We present Kepler satellite photometry of KIC 10661783, a short-period binary star system which shows total eclipses and multi-periodicScuti pulsations. A frequency analysis of the eclipse-subtracted


Pulsations of the Oe Star ζ Ophiuchi from MOST Satellite Photometry and Ground-based Spectroscopy
Twenty-four days of highly precise Microvariability and Oscillations of Stars (MOST) satellite photometry obtained in mid-2004 of the rapidly rotating O9.5 V star ζ Oph have yielded at least a dozen
