Fundamental stellar and accretion disc parameters of the eclipsing binary DQ Velorum
D. Barría, R. E. Mennickent, L. Schmidtobreick +5
To add to the growing collection of well-studied double periodic variables (DPVs) we have carried out the first spectroscopic and photometric analysis of the eclipsing binary DQ Ve…
An asteroseismic study of the Southern Cephei star \astrobj{ALS 3721}
C. Ulusoy, E. Niemczura, B. Ulaş +1
We present the results of a new investigation aimed to identify the pulsational characteristics of the Southern Cephei star ALS 3721. Spectroscopic and multicolour photometric…
Spectroscopic and Photometric Observations of Kepler Asteroseismic Targets
J. Molenda-Zakowicz, M. Jerzykiewicz, G. Kopacki +10
We summarize our ground-based program of spectroscopic and photometric observations of the asteroseismic targets of the Kepler space telescope. We have already determined atmospher…
Multi-ring structure of the eclipsing disk in EE Cep - possible planets?
C. Galan, M. Mikolajewski, T. Tomov +57
The photometric and spectroscopic observational campaign organized for the 2008/9 eclipse of EE Cep revealed features, which indicate that the eclipsing disk in the EE Cep system h…
