Searching for transit timing variations in transiting exoplanet systems
Marie Hrudková, Ian Skillen, Chris Benn +5
Searching for transit timing variations in the known transiting exoplanet systems can reveal the presence of other bodies in the system. Here we report such searches for two transi…
High-precision elements of double-lined spectroscopic binaries from combined interferometry and spectroscopy. Application to the beta Cephei star beta Centauri
M. Ausseloos, C. Aerts, K. Lefever +2
We present methodology to derive high-precision estimates of the fundamental parameters of double-lined spectroscopic binaries. We apply the methods to the case study of the double…
Pulsating Components in Close Binaries
Conny Aerts, Petr Harmanec
We present an overview of pulsating stars in close binaries, focusing on the question what role the dupliticity plays in triggering and/or modifying stellar oscillations and on how…
The orbit of the close spectroscopic binary epsilon Lupi and the intrinsic variability of its early B-type components
K. Uytterhoeven, P. Harmanec, J. H. Telting +1
We subjected 106 new high-resolution spectra of the double-lined spectroscopic close binary epsilon Lupi, obtained in a time-span of 17 days from two different observatories, to a…
Properties and nature of Be stars XXIII. Long-term variations and physical properties of kappa Dra
S. M. Saad, J. Kubat, P. Koubsky +9
We present an analysis of new spectroscopic observations of the bright Be star kappa Dra obtained at the Ondrejov observatory during 1992 - 2003 and UBV photometric observations se…
Properties and nature of Be stars. XX. Binary nature and orbital elements of gamma Cas
P. Harmanec, P. Habuda, S. Stefl +8
An analysis of accurate radial velocities (RVs) of the Be star gamma Cas from 295 Reticon spectrograms secured between October 1993 and May 2000 allowed us to prewhiten the RVs for…
