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...

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...

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...

We report on the ground-based follow-up program of spectroscopic and photometric observations of solar-like asteroseismic targets for the Kepler space mission...

The preliminary results of a multisite photometric campaign on the Pleiades Delta Scuti variable V650 Tauri are reported. The star was observed photometrically...

Kepler asteroseismology has played an important role in the characterization of host stars and their planetary systems. Target selection biases, however, meant...
