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…
The optical afterglow and host galaxy of GRB000926
J. U. Fynbo, J. Gorosabel, T. H. Dall +27
We present the discovery of the Optical Transient (OT) of the long-duration gamma-ray burst GRB000926. The optical transient was detected independently with the Nordic Optical Tele…
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…
