Oscillations in Procyon A: First results from a multi-site campaign
S. Hekker, T. Arentoft, H. Kjeldsen +45
Procyon A is a bright F5IV star in a binary system. Although the distance, mass and angular diameter of this star are all known with high precision, the exact evolutionary state is…
Amplitude Ratios as Mode Characterizors in delta Scuti stars
J. R. Rasmussen, T. H. Dall, S. Frandsen
Seismology of delta Scuti stars holds great potentials for testing theories of stellar structure and evolution. The ratio of mode amplitudes in light and in equivalent width of spe…
Confirmation of Solar-Like Oscillations in eta Bootis
H. Kjeldsen, T. R. Bedding, I. K. Baldry +9
We report observations of the G0 subgiant eta Boo made in 1998, in Balmer-line equivalent width with the 2.5-m Nordic Optical Telescope and in velocity with the 24-inch Lick CAT. I…
Oscillation mode identifications and models for the delta Scuti star FG Virginis
M. Viskum, H. Kjeldsen, T. R. Bedding +4
We present new spectroscopic and photometric time series observations of the delta Scuti star FG~Vir. We detect the oscillations via changes in the equivalent widths of hydrogen an…
A search for solar-like oscillations in alpha Cen A
Timothy R. Bedding, Hans Kjeldsen, S. Frandsen +1
We have been using a new method to search for solar-like oscillations that involves measuring temperature changes via their effect on the equivalent widths of the Balmer hydrogen l…
