Mysterious eclipses in the light-curve of KIC8462852: a possible explanation
L. Neslusan, J. Budaj
Apart from thousands of `regular' exoplanet candidates, Kepler satellite has discovered a few stars exhibiting peculiar eclipse-like events. They are most probably caused by disint…
Simultaneous X-ray and radio observations of the radio-mode switching pulsar PSR B1822-09
W. Hermsen, L. Kuiper, J. W. T. Hessels +7
We report on simultaneous X-ray and radio observations of the radio-mode-switching pulsar PSR B1822-09 with ESA's XMM-Newton and the WSRT, GMRT and Lovell radio telescopes. PSR B18…
Radiation Pattern of Radio and Optical Components of Extended Radio Sources
V. R. Amirkhanyan
The relation between parameters the D/sqrt(I) and Ic/Isum and radiation patterns of the optical and radio components of an extended radio source is analyzed, where D and I are the…
Transition from Fireball to Poynting-flux-dominated Outflow in Three-Episode GRB 160625B
B. -B. Zhang, B. Zhang, A. J. Castro-Tirado +51
The ejecta composition is an open question in gamma-ray bursts (GRB) physics. Some GRBs possess a quasi-thermal spectral component in the time-resolved spectral analysis, suggestin…
Constraining models of twin peak quasi-periodic oscillations with realistic neutron star equations of state
Gabriel Török, Kateřina Goluchová, Martin Urbanec +8
Twin-peak quasi-periodic oscillations (QPOs) are observed in the X-ray power-density spectra of several accreting low-mass neutron star (NS) binaries. In our previous work we have…
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…
The accretion rate dependence of burst oscillation amplitude
Laura S. Ootes, Anna L. Watts, Duncan K. Galloway +1
Neutron stars in low mass X-ray binaries exhibit oscillations during thermonuclear bursts, attributed to asymmetric brightness patterns on the burning surfaces. All models that hav…
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…
On the Connection of Gamma-Ray Bursts and X-Ray Flashes in the BATSE and RHESSI Databases
Jakub Řípa, Attila Mészáros
Classification of gamma-ray bursts (GRBs) into groups has been intensively studied by various statistical tests in previous years. It has been suggested that there was a distinct g…
Two Groups of Red Giants with Distinct Chemical Abundances in the Bulge Globular Cluster NGC 6553 Through the Eyes of APOGEE
Baitian Tang, Roger E. Cohen, Doug Geisler +18
Multiple populations revealed in globular clusters (GCs) are important windows to the formation and evolution of these stellar systems. The metal-rich GCs in the Galactic bulge are…
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…
SDSS IV MaNGA: The global and local stellar mass assemby histories of galaxies
Héctor J. Ibarra-Medel, Sebastián F. Sánchez, Vladimir Avila-Reese +10
By means of the fossil record method implemented through Pipe3D, we reconstruct the global and radial stellar mass growth histories (MGHs) of an unprecedentedly large sample of gal…
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…
Stellar nuclei and inner polar disks in lenticular galaxies
Olga K. Sil'chenko
I analyze statistics of the stellar population properties for stellar nuclei and bulges of nearby lenticular galaxies in different environments by using panoramic spectral data of…
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…
SDSS-IV MaNGA: Faint quenched galaxies I- Sample selection and evidence for environmental quenching
Samantha J. Penny, Karen L. Masters, Anne-Marie Weijmans +21
Using kinematic maps from the Sloan Digital Sky Survey (SDSS) Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, we reveal that the majority of low-mass quenched g…
An accreting pulsar with extreme properties drives an ultraluminous x-ray source in NGC 5907
G. L. Israel, A. Belfiore, L. Stella +20
Ultraluminous x-ray sources (ULXs) in nearby galaxies shine brighter than any X-ray source in our Galaxy. ULXs are usually modeled as stellar-mass black holes (BHs) accreting at ve…
