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...
Asteroseismology of massive stars in the young open cluster NGC 884: a status report
To improve our comprehension of the β Cephei stars, we set up a photometric multi-site campaign on the open cluster NGC 884 (χ Persei). Thirteen telescopes...
Asteroseismology of OB stars with hundreds of single snapshot spectra (and a few time-series of selected targets)
Imagine we could do asteroseismology of large samples of OB-type stars by using just one spectrum per target. That would be great! But this is probably a crazy...
Asteroseismology of solar-type stars with Kepler I: Data analysis
We report on the first asteroseismic analysis of solar-type stars observed by Kepler. Observations of three G-type stars, made at one-minute cadence during the...
Asteroseismology of solar-type stars with Kepler: III. Ground-based data
We report on the ground-based follow-up program of spectroscopic and photometric observations of solar-like asteroseismic targets for the Kepler space mission...
