We have analyzed data from a multi-site campaign to observe oscillations in the F5 star Procyon. The data consist of high-precision velocities that we obtained over more than three weeks with eleven telescopes. A new method for adjusting the data wei

SPB stars in the open SMC cluster NGC 371

Autor: Karoff, C., Arentoft, T., Glowienka, L., Coutures, C., Nielsen, T. B., Dogan, G., Grundahl, F., Kjeldsen, H.

Pulsation in beta Cep and SPB stars are driven by the kappa mechanism which depends critically on the metallicity. It has therefore been suggested that beta Cep and SPB stars should be rare in the Magellanic Clouds which have lower metallicities than

Oscillating Blue Stragglers, gamma Doradus stars and eclipsing binaries in the open cluster NGC2506

This is the first step in a project to combine studies of eclipsing binaries and oscillating stars to probe the interior of Blue Stragglers (BS). This may imply a way to discriminate observationally between different birth mechanisms of BS stars. We
