Tidal effects and periastron events in binary stars
Gloria Koenigsberger, Edmundo Moreno
Binary stars in eccentric orbits are frequently reported to present increasing levels of activity around periastron passage. In this paper we present results of a calculation from…
Tidal Flows from Asynchronous Rotation in Binaries
Gloria Koenigsberger, Edmundo Moreno, David Harrington
Asynchronous rotation in binary stars produces non-radial oscillations that are known to cause observable variability on orbital timescales. The horizontal perturbations of the sur…
First detection of phase-dependent colliding wind X-ray emission outside the Milky Way
Yael Naze, Michael F. Corcoran, Gloria Koenisgberger +1
After having reported the detection of X-rays emitted by the peculiar system HD5980, we assess here the origin of this high-energy emission from additional X-ray observations obtai…
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…
The X-ray binary 2S0114+650=LSI+65 010:A slow pulsar or tidally-induced pulsations?
G. Koenigsberger, L. Georgiev, E. Moreno +3
The X-ray source 2S0114+650=LSI+65 010 is a binary system containing a B-type primary and a low mass companion believed to be a neutron star. The system has three reported periodic…
FUSE observations of HD 5980: The wind structure of the eruptor
Gloria Koenigsberger, Alexander W. Fullerton, Derck Massa +1
HD 5980 is a unique system containing one massive star (star A) that is apparently entering the luminous blue variable phase, and an eclipsing companion (star B) that may have alre…
