Orbital solutions derived from radial velocities and time delays for four {\it Kepler} systems with A/F-type (candidate) hybrid pulsators
P. Lampens, L. Vermeylen, Y. Frémat +8
The presence of A/F-type {\it Kepler} hybrid stars extending across the entire Sct- Dor instability strips and beyond remains largely unexplained. In order to better underst…
Multi-technique investigation of the binary fraction among A-F type candidate hybrid variable stars discovered by Kepler
P. Lampens, Y. Frémat, L. Vermeylen +14
Hundreds of candidate hybrid pulsators of intermediate type A-F were revealed by the recent space missions. Hybrid pulsators allow to study the full stellar interiors, where p- and…
Physical properties of seven binary and higher-order multiple OB systems
Pavel Mayer, Petr Harmanec, Rolf Chini +7
Analyses of multi-epoch, high-resolution (~ 50000) optical spectra of seven early-type systems provided various important new insights with respect to their multiplicity. First det…
Luminous blue variables: An imaging perspective on their binarity and near environment
Christophe Martayan, Alex Lobel, Dietrich Baade +18
Context. Luminous blue variables (LBVs) are rare massive stars with very high luminosity. They are characterized by strong photo-metric and spectroscopic variability related to tra…
Modelling the asymmetric wind of the luminous blue variable binary MWC 314
A. Lobel, J. H. Groh, C. Martayan +12
We present a spectroscopic analysis of MWC 314, a luminous blue variable (LBV) candidate with an extended bipolar nebula. The detailed spectroscopic variability is investigated to…
Detection of a large sample of Gamma Dor stars from Kepler space photometry and high-resolution ground-based spectroscopy
A. Tkachenko, C. Aerts, A. Yakushechkin +10
The space-missions MOST, CoRoT, and Kepler deliver a huge amount of high-quality photometric data suitable to study numerous pulsating stars. Our ultimate goal is a detection and a…
