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…
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…
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…
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…
The Physical Nature and Orbital Behavior of the Eclipsing System DK Cygni
Jae Woo Lee, Jae-Hyuck Youn, Jang-Ho Park +1
New CCD photometry is presented for the hot overcontact binary DK Cyg, together with reasonable explanations for the light and period variations. Historical light and velocity curv…
New Constraints on the Star Formation History of the Star Cluster NGC 1856
Matteo Correnti, Paul Goudfrooij, Thomas H. Puzia +1
We use the Wide Field Camera 3 onboard the Hubble Space Telescope to obtain deep, high-resolution photometry of the young (age ~ 300 Myr) star cluster NGC1856 in the Large Magellan…
A new study of an old sink of sulfur in hot molecular cores: the sulfur residue
Paul M. Woods, Angela Occhiogrosso, Serena Viti +3
Sulfur appears to be depleted by an order of magnitude or more from its elemental abundance in star-forming regions. In the last few years, numerous observations and experiments ha…
