Evolved stars as donors in symbiotic binaries
A. Skopal, M. Sekeras, N. Shagatova
This contribution is focused on the role of cool giants in symbiotic binaries. Especially, we pay attention to their mass-loss rates and the wind mass-transfer onto their compact a…
V1006 Cygni: Dwarf Nova Showing Three Types of Outbursts and Simulating Some Features of the WZ Sge-Type Behavior
Taichi Kato, Elena P. Pavlenko, Alisa V. Shchurova +17
We observed the 2015 July-August long outburst of V1006 Cyg and established this object to be an SU UMa-type dwarf nova in the period gap. Our observations have confirmed that V100…
Spectroscopic view on the outburst activity of the symbiotic binary AG Draconis
Laurits Leedjärv, Rudolf Gális, Ladislav Hric +2
Variations of the emission lines in the spectrum of the yellow symbiotic star AG Dra have been studied for over 14 years (1997 - 2011), using more than 500 spectra obtained on the…
Long-term trends of magnetic bright points: I. Number of MBPs at disc centre
D. Utz, R. Muller, S. Thonhofer +5
Context. The Sun shows an activity cycle that is caused by its varying global magnetic field. During a solar cycle, sunspots, i.e. extended regions of strong magnetic fields, occur…
Stellar atmosphere interpolator for empirical and synthetic spectra
Nikolay Podorvanyuk, Igor Chilingarian, Ivan Katkov
We present a new stellar atmosphere interpolator which we will use to compute stellar population models based on empirical and/or synthetic spectra. We combined observed and synthe…
OSSOS II: A Sharp Transition in the Absolute Magnitude Distribution of the Kuiper Belt's Scattering Population
C. Shankman, J. J. Kavelaars, B. J. Gladman +8
We measure the absolute magnitude, , distribution, of the scattering Trans-Neptunian Objects (TNOs) as a proxy for their size-frequency distribution. We…
The Outer Solar System Origins Survey: I. Design and First-Quarter Discoveries
Michele T. Bannister, J. J. Kavelaars, Jean-Marc Petit +36
We report the discovery, tracking and detection circumstances for 85 trans-Neptunian objects (TNOs) from the first 42 deg of the Outer Solar System Origins Survey (OSSOS). Th…
The relative wavelength independence of IR lags in active galactic nuclei: implications for the distribution of the hot dust
V. L. Oknyansky, C. M. Gaskell, E. V. Shimanovskaya
We show that, contrary to simple predictions, most AGNs show at best only a small increase of lags in the J, H, K, and L bands with increasing wavelength. We suggest that a possibl…
Mass-loss rate by the Mira in the symbiotic binary V1016 Cygni from Raman scattering
Matej Sekeráš, Augustin Skopal
The mass-loss rate from Mira variables represents a key parameter in our understanding of their evolutionary tracks. We introduce a method for determining the mass-loss rate from t…
On the Atmospheric Extinction Reduction Procedure in Multiband Wide-Field Photometric Surveys
A. Zakharov, A. Mironov, A. Biryukov +8
We propose an improved method for the atmospheric extinction reduction within optical photometry. Our method is based on the simultaneous multicolor observations of photometric sta…
Combinatorial Intricacies of Labeled Fano Planes
Metod Saniga
Given a seven-element set , there are 30 ways to define a Fano plane on it. Let us call a line of such Fano plane, that is to say an unordered triple from $X…
Ground-based transit observations of the HAT-P-18, HAT-P-19, HAT-P-27/WASP-40 and WASP-21 systems
M. Seeliger, M. Kitze, R. Errmann +46
As part of our ongoing effort to investigate transit timing variations (TTVs) of known exoplanets, we monitored transits of the four exoplanets HAT-P-18b, HAT-P-19b, HAT-P-27b/WASP…
Observations of Comets C/2007 D1 (LINEAR), C/2007 D3 (LINEAR), C/2010 G3 (WISE), C/2010 S1 (LINEAR), and C/2012 K6 (McNaught) at large heliocentric distances
Oleksandra Ivanova, Luboš Neslušan, Zuzana Seman Krišandova +5
Photometric and spectroscopic observations of five nearly parabolic comets with eccentricity larger than 0.99 at heliocentric distances greater than 4 AU were performed. No molecul…
Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae. VII: The Seventh Year (2014-2015)
Taichi Kato, Franz-Josef Hambsch, Pavol A. Dubovsky +89
Continuing the project described by Kato et al. (2009, arXiv:0905.1757), we collected times of superhump maxima for 102 SU UMa-type dwarf novae observed mainly during the 2014-2015…
WASP-14 b: Transit Timing analysis of 19 light curves
St. Raetz, G. Maciejewski, M. Seeliger +11
Although WASP-14 b is one of the most massive and densest exoplanets on a tight and eccentric orbit, it has never been a target of photometric follow-up monitoring or dedicated obs…
Galactic Center Minispiral: Interaction Modes of Neutron Stars
Michal Zajacek, Vladimir Karas, Devaky Kunneriath
Streams of gas and dust in the inner parsec of the Galactic center form a distinct feature known as the Minispiral, which has been studied in radio waveband as well as in the infra…
Probing the MSP prenatal stage: the optical identification of the X-ray burster EXO 1745-248 in Terzan 5
F. R. Ferraro, C. Pallanca, B. Lanzoni +5
We report on the optical identification of the neutron star burster EXO 1745-248 in Terzan 5. The identification was performed by exploiting HST/ACS images acquired in Director's D…
