Oscillation Maps in the Broadband Radio Spectrum of the 1 August 2010 Event
M. Karlicky, J. Rybak
We search for indications of waves in the 25-2000 MHz radio spectrum of the 1 August 2010 event (SOL2010-08-01T08:57:00L075C013), where fast propagating waves in the solar corona w…
BONNSAI: correlated stellar observables in Bayesian methods
F. R. N. Schneider, N. Castro, L. Fossati +2
In an era of large spectroscopic surveys of stars and big data, sophisticated statistical methods become more and more important in order to infer fundamental stellar parameters su…
Superoutburst of WZ Sge-type Dwarf Nova Below the Period Minimum: ASASSN-15po
Kosuke Namekata, Keisuke Isogai, Taichi Kato +38
We report on a superoutburst of a WZ Sge-type dwarf nova (DN), ASASSN-15po. The light curve showed the main superoutburst and multiple rebrightenings. In this outburst, we observed…
RZ Leonis Minoris Bridging between ER Ursae Majoris-Type Dwarf Nova and Novalike System
Taichi Kato, Ryoko Ishioka, Keisuke Isogai +64
We observed RZ LMi, which is renowned for the extremely (~19d) short supercycle and is a member of a small, unusual class of cataclysmic variables called ER UMa-type dwarf novae, i…
Broadband microwave sub-second pulsations in an expanding coronal loop of the 2011 August 10 flare
Hana Meszarosova, Jan Rybak, Larisa Kashapova +3
We studied the characteristic physical properties and behavior of broadband microwave sub-second pulsations observed in an expanding coronal loop during the GOES C2.4 solar flare o…
Proton heating by pick-up ion driven cyclotron waves in the outer heliosphere: Hybrid expanding box simulations
Petr Hellinger, Pavel M. Travnicek
Using one-dimensional hybrid expanding box model we investigate properties of the solar wind in the outer heliosphere. We assume a proton-electron plasma with a strictly transverse…
Spectropolarimetric observations of an arch filament system with the GREGOR solar telescope
H. Balthasar, P. Gömöry, S. J. González Manrique +27
Arch filament systems occur in active sunspot groups, where a fibril structure connects areas of opposite magnetic polarity, in contrast to active region filaments that follow the…
Flares on A-type stars: Evidence for heating of solar corona by nanoflares?
M. Svanda, M. Karlicky
We analyzed the occurrence rates of flares on stars of spectral types K, G, F, and A, observed by Kepler. We found that the histogram of occurrence frequencies of stellar flares is…
Optical flare activity in the low-mass eclipsing binary GJ~3236
S. Parimucha, P. Dubovsky, M. Vanko +1
We present our observations of the low-mass eclipsing binary GJ~3236. We have analyzed a phased light-curve and confirmed previously determined fundamental parameters of the…
Chemical Abundances in a Sample of Red Giants in the Open Cluster NGC 2420 from APOGEE
Diogo Souto, Katia Cunha, Verne Smith +20
NGC 2420 is a 2 Gyr-old well-populated open cluster that lies about 2 kpc beyond the solar circle, in the general direction of the Galactic anti-center. Most previous abundan…
Long-Term Photometry of IC 348 with the YETI Network
D. J. Fritzewski, M. Kitze, M. Mugrauer +29
We present long-term photometric observations of the young open cluster IC 348 with a baseline time-scale of 2.4 yr. Our study was conducted with several telescopes from the Young…
Magnetic cycles of Sun-like stars with different levels of coronal and chromospheric activity -- comparison with the Sun
E. A. Bruevich, V. V. Bruevich, E. V. Shimanovskaya
The atmospheric activity of the Sun and Sun-like stars is analyzed involving observations from HK-project at the Mount Wilson Observatory, the California and Carnegie Planet Search…
Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae. VIII: The Eighth Year (2015-2016)
Taichi Kato, Franz-Josef Hambsch, Berto Monard +75
Continuing the project described by Kato et al. (2009, arXiv:0905.1757), we collected times of superhump maxima for 128 SU UMa-type dwarf novae observed mainly during the 2015-2016…
PM J03338+3320: Long-Period Superhumps in Growing Phase Following a Separate Precursor Outburst
Taichi Kato, Enrique de Miguel, William Stein +12
We observed the first-ever recorded outburst of PM J03338+3320, the cataclysmic variable selected by proper-motion survey. The outburst was composed of a precursor and the main sup…
Fitting peculiar spectral profiles in He I 10830 Å absorption features
S. J. González Manrique, C. Kuckein, A. Pastor Yabar +28
The new generation of solar instruments provides better spectral, spatial, and temporal resolution for a better understanding of the physical processes that take place on the Sun.…
Wind mass transfer in S-type symbiotic binaries II. Indication of wind focusing
Natalia Shagatova, Augustin Skopal, Zuzana Carikova
Context. The wind mass transfer from a giant to its white dwarf companion in symbiotic binaries is not well understood. For example, the efficiency of wind mass transfer of the can…
Chromospheric evaporation flows and density changes deduced from Hinode/EIS during an M1.6 flare
P. Gömöry, A. M. Veronig, Y. Su +2
We analyzed high-cadence sit-and-stare observations acquired with the Hinode/EIS spectrometer and HXR measurements acquired with RHESSI during an M-class flare. During the flare im…
