Rotational properties of single and wide binary subdwarf B stars
S. Geier, U. Heber, H. Edelmann +2
We measured projected rotational velocities of more than a hundred apparently single sdBs. A comparison is made with sdB stars in binary systems with orbits so wide, that tidal int…
Plasma diagnostics of an EIT wave observed by Hinode/EIS and SDO/AIA
A. M. Veronig, P. Gomory, I. W. Kienreich +4
We present plasma diagnostics of an EIT wave observed with high cadence in Hinode/EIS sit-and-stare spectroscopy and SDO/AIA imagery obtained during the HOP-180 observing campaign…
Modelling of the ultraviolet and visual SED variability in the hot magnetic Ap star CU Vir
J. Krticka, Z. Mikulasek, T. Luftinger +4
The spectral energy distribution (SED) in chemically peculiar stars may be significantly affected by their abundance anomalies. The observed SED variations are usually assumed to b…
Variability of Hot Post-AGB Star IRAS 19336-0400 in the Early Phase of its Planetary Nebula Ionization
V. P. Arkhipova, M. A. Burlak, V. F. Esipov +2
We present photoelectric and spectral observations of a hot candidate proto-planetary nebula - early B-type supergiant with emission lines in spectrum - IRAS 19336-0400. The light…
Abundance analysis of Am binaries and search for tidally driven abundance anomalies - III. HD116657, HD138213, HD155375, HD159560, HD196544 and HD204188
I. Stateva, I. Kh. Iliev, J. Budaj
We continue here the systematic abundance analysis of a sample of Am binaries in order to search for possible abundance anomalies driven by tidal interaction in these binary system…
Formation of a disk structure in the symbiotic binary AX Per during its 2007-10 precursor-type activity
A. Skopal, T. N. Tarasova, Z. Cariková +12
AX Per is an eclipsing symbiotic binary. During active phases, deep narrow minima are observed in its light curve, and the ionization structure in the binary changes significantly.…
Surprising variations in the rotation of the chemically peculiar stars CU Virginis and V901 Orionis
Zdenek Mikulasek, Jiri Krticka, Gregory W. Henry +13
CU Vir and V901 Ori belong among these few magnetic chemically peculiar stars whose rotation periods vary on timescales of decades. We aim to study the stability of the periods in…
Formation of neutral disk-like zone around the active hot stars in symbiotic binaries
Zuzana Carikova, Augustin Skopal
In this contribution we present the ionization structure in the enhanced wind from the hot star in symbiotic binaries during active phases. Rotation of the hot star leads to the co…
Ensemble asteroseismology of red-giant stars
S. Hekker, R. L. Gilliland, Sarbani Basu +3
The successful launches of the CoRoT and Kepler space missions have led to the detections of solar-like oscillations in large samples of red-giant stars. The large numbers of red g…
A new flare star member candidate in the Pleiades cluster
M. Moualla, T. O. B. Schmidt, R. Neuhäuser +19
We present a new flare star, which was discovered during our survey on a selected field at the edge of the Pleiades cluster. The field was observed in the period 2007 - 2010 with t…
Synthetic Spectra and Light Curves of Interacting Binaries and Exoplanets with Circumstellar Material: SHELLSPEC
Jan Budaj
Program SHELLSPEC is designed to calculate light-curves, spectra and images of interacting binaries and extrasolar planets immersed in a moving circumstellar environment which is o…
Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae. III: The Third Year (2010--2011)
Taichi Kato, Hiroyuki Maehara, Ian Miller +75
Continuing the project described by Kato et al. (2009, PASJ 61, S395, arXiv:0905.1757), we collected times of superhump maxima for 51 SU UMa-type dwarf novae mainly observed during…
Effects of dust on light-curves of εAur type stars
J. Budaj
εAuriga is one of the most mysterious objects on the sky. Prior modeling of its light-curve assumed a dark, inclined, non-transparent or semi-transparent, dusty disk with a central…
Young Exoplanet Transit Initiative (YETI)
R. Neuhäuser, R. Errmann, A. Berndt +80
We present the Young Exoplanet Transit Initiative (YETI), in which we use several 0.2 to 2.6m telescopes around the world to monitor continuously young (< 100 Myr), nearby (< 1 kpc…
The nearby eclipsing stellar system delta Velorum III. Self-consistent fundamental parameters and distance
A. Merand, P. Kervella, T. Pribulla +6
The triple stellar system delta Vel (composed of two A-type and one F-type main sequence stars) is particularly interesting as it contains one of the nearest and brightest eclipsin…
The nearby eclipsing stellar system delta Velorum. II. First reliable orbit for the eclipsing pair
T. Pribulla, A. Merand, P. Kervella +8
Context. The nearby multiple system delta Velorum contains a widely detached eclipsing binary and a third component. Aims. We take advantage of this system offering the opportunity…
