The excitation of solar-like oscillations in a δ Sct star by efficient envelope convection
Delta Scuti (δ Sct)1 stars are opacity-driven pulsators with masses of 1.5–2.5M⊙, their pulsations resulting from the varying ionization of helium. In less massive stars2 such as the Sun, convection transports ma...

Late-Type Active Stars: Rotation & Companions
Rapid rotation has been established empirically as the controlling factor for the magnetic field strength and the magnetic activity level of single late-type (F-M) stars. The dynamo theories explain this fact ...

Abundance Variations in NGC 288, NGC 362 and NGC 1851
Strömgren uvby photometry is a powerful tool to study abundance variations in globular clusters through the c 1 and m 1 indices. This is because the NH (3360Å) and ...

Studying Old Open Clusters with Detached Eclipsing Binaries
The single most important parameter which determines the evolution of a star is its mass. Detached eclipsing binaries offer the possibility to determine accurate masses and radii for their components. By study...
