Multiperiodicity in quasi-periodic pulsations of flare hard X-rays: a case study
M. Tomczak, Z. Szaforz
We present a case study of the solar flare (SOL2001-10-02T17:31) that showed quasi-periodic pulsations (QPPs) in hard X-rays with two simultaneously excited periods, P_1 = 26-31 s…
Structure and Dynamics of the 13/14 November 2012 Eclipse White-Light Corona
Jay M. Pasachoff, Vojtech Rusin, Metod Saniga +9
Continuing our series of observations of the motion and dynamics of the solar corona over the solar-activity cycle, we observed the corona from sites in Queensland, Australia, duri…
Automated determination of g-mode period spacing of red-giant stars
Abhisek Datta, Anwesh Mazumdar, Umang Gupta +1
The Kepler satellite has provided photometric timeseries data of unprecedented length, duty cycle and precision. To fully analyse these data for the tens of thousands of stars obse…
The Structure of Pre-transitional Protoplanetary Disks. II. Azimuthal Asymmetries, Different Radial Distributions of Large and Small Dust Grains in PDS~70
J. Hashimoto, T. Tsukagoshi, J. M. Brown +54
The formation scenario of a gapped disk, i.e., transitional disk, and its asymmetry is still under debate. Proposed scenarios such as disk-planet interaction, photoevaporation, gra…
Wind mass transfer in S-type symbiotic binaries I. Focusing by the wind compression model
Augustin Skopal, Zuzana Carikova
Context: Luminosities of hot components in symbiotic binaries require accretion rates that are higher than those that can be achieved via a standard Bondi-Hoyle accretion. This imp…
The applicability of the wind compression model
Zuzana Cariková, Augustin Skopal
Compression of the stellar winds from rapidly rotating hot stars is described by the wind compression model. However, it was also shown that rapid rotation leads to rotational dist…
Transit timing of TrES-2: a combined analysis of ground- and space-based photometry
St. Raetz, G. Maciejewski, Ch. Ginski +21
Homogeneous observations and careful analysis of transit light curves can lead to the identification of transit timing variations (TTVs). TrES-2 is one of few exoplanets, which off…
The Three body system delta Circini
P. Mayer, P. Harmanec, H. Sana +1
Delta Cir is known as an O7.5 III eclipsing and spectroscopic binary with an eccentric orbit. Penny et al. discovered the presence of a third component in the IUE spectra. The ecli…
Multiwavelength modelling the SED of supersoft X-ray sources III. RS Ophiuchi: The supersoft X-ray phase and beyond
A. Skopal
I modelled the 14 Å- 37 m SED of the recurrent symbiotic nova RS Oph during its supersoft source (SSS) phase and the following quiescent phase. During the SSS phase, the model S…
Early evolution of the extraordinary Nova Del 2013 (V339 Del)
A. Skopal, H. Drechsel, T. N. Tarasova +14
We determine the temporal evolution of the luminosity L(WD), radius R(WD) and effective temperature Teff of the white dwarf (WD) pseudophotosphere of V339 Del from its discovery to…
Superoutburst of SDSS J090221.35+381941.9: First Measurement of Mass Ratio in an AM CVn-Type Object using Growing Superhumps
Taichi Kato, Tomohito Ohshima, Denis Denisenko +36
We report on a superoutburst of the AM CVn-type object SDSS J090221.35+381941.9 [J0902; orbital period 0.03355(6) d] in 2014 March-April. The entire outburst consisted of a precurs…
Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae. VI: The Sixth Year (2013-2014)
Taichi Kato, Pavol A. Dubovsky, Igor Kudzej +83
Continuing the project described by Kato et al. (2009, PASJ, 61, S395, arXiv:0905.1757), we collected times of superhump maxima for 56 SU UMa-type dwarf novae mainly observed durin…
Outburst activity of symbiotic system AGDra
Ladislav Hric, Rudolf Galis, Laurits Leedjarv +2
AG Dra is a well known bright symbiotic binary with a white dwarf and a pulsating red giant. The long-term photometry monitoring and a new behaviour of the system are presented. Th…
Plasma heating in solar flares and their soft and hard X-ray emissions
R. Falewicz
In this paper, the energy budgets of two single-loop like flares observed in X- ray are analysed under the assumption that non-thermal electrons (NTEs) are the only source of plasm…
Solar Wind Electron Strahls Associated with a High-Latitude CME: \emph{Ulysses} Observations
M. Lazar, J. Pomoell, S. Poedts +2
Counterstreaming beams of electrons are ubiquitous in coronal mass ejections (CMEs) - although their existence is not unanimously accepted as a necessary and/or sufficient signatur…
Solar Flare Composition and Thermodynamics from RESIK X-ray Spectra
B. Sylwester, J. Sylwester, K. J. H. Phillips +2
Previous estimates of the solar flare abundances of Si, S, Cl, Ar, and K from the RESIK X-ray crystal spectrometer on board the CORONAS-F spacecraft were made on the assumption of…
The Clusters AgeS Experiment (CASE). VI. Analysis of two detached eclipsing binaries in the Globular Cluster M55
J. Kaluzny, I. B. Thompson, A. Dotter +4
We present an analysis of the detached eclipsing binaries V44 and V54 belonging to the globular cluster M55. For V54 we obtain the following absolute parameters: $M_p=0.726\pm 0.01…
Investigation of a transiting planet candidate in Trumpler 37: an astrophysical false positive eclipsing spectroscopic binary star
R. Errmann, G. Torres, T. O. B. Schmidt +50
We report our investigation of the first transiting planet candidate from the YETI project in the young (~4 Myr old) open cluster Trumpler 37. The transit-like signal detected in t…
Multiwavelength modelling the SED of supersoft X-ray sources. II. RS Ophiuchi: From the explosion to the SSS phase
