Oscillating Blue Stragglers, gamma Doradus stars and eclipsing binaries in the open cluster NGC2506
T. Arentoft, J. De Ridder, F. Grundahl +9
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 discrimina…

A line profile analysis of the pulsating red giant star epsilon Ophiuchi (G9.5III)
S. Hekker, C. Aerts, J. De Ridder +1
So far, solar-like oscillations have been studied using radial velocity and/or light curve variations, which reveal frequencies of the oscillation modes. Line-profile variations, h…
