The warm absorber in NGC 5548: The lean years
R. G. Detmers, J. S. Kaastra, E. Costantini +2
We study the variability of the warm absorber and the gas responsible for the emission lines in the Seyfert 1 galaxy NGC 5548, in order to constrain the location and physical prope…
Gamma-Ray Bursts from tidally spun-up Wolf-Rayet stars?
R. G. Detmers, N. Langer, Ph. Podsiadlowski +1
The collapsar model requires rapidly rotating Wolf-Rayet stars as progenitors of long gamma-ray bursts. However, Galactic Wolf-Rayet stars rapidly lose angular momentum due to thei…
Tides in asynchronous binary systems
Oswaldo Toledano, Edmundo Moreno, Gloria Koenigsberger +2
Stellar oscillations are excited in non-synchronously rotating stars in binary systems due to the tidal forces. Tangential components of the tides can drive a shear flow which beha…
