Spectral Characteristics of the He I D3 Line in a Quiescent Prominence Observed by THEMIS
J. Koza, J. Rybák, P. Gömöry +2
We analyze the observations of a quiescent prominence acquired by the Telescope Heliographique pour l'Etude du Magnetisme et des Instabilites Solaires (THEMIS) in the He I 5876 A (…
Transmission profile of the Dutch Open Telescope H Lyot filter
J. Koza, R. H. Hammerschlag, J. Rybák +3
Accurate knowledge of the spectral transmission profile of a Lyot filter is important, in particular in comparing observations with simulated data. The paper summarizes available f…
Light-curve analysis of KOI 2700b: the second extrasolar planet with a comet-like tail
Z. Garai
The Kepler object KOI 2700b (KIC 8639908b) was discovered recently as the second exoplanet with a comet-like tail. It exhibits a distinctly asymmetric transit profile, likely indic…
Accurate photometry with digitized photographic plates of the Moscow collection
K. V. Sokolovsky, A. M. Zubareva, D. M. Kolesnikova +3
Photographic plate archives contain a wealth of information about positions and brightness celestial objects had decades ago. Plate digitization is necessary to make this informati…
Different accretion heating of the neutron star crust during multiple outbursts in MAXI J0556-332
A. S. Parikh, J. Homan, R. Wijnands +11
The transient neutron star (NS) low-mass X-ray binary MAXI J0556332 provides a rare opportunity to study NS crust heating and subsequent cooling for multiple outbursts of the sa…

A. M. Cherepashchuk, N. A. Katysheva, T. S. Khruzina +4
Photometric observations of the low-mass X-ray binary system A0620-00=V616 Mon are performed in the optical (unfiltered light, lambda_eff~6400A) and the near-infrared J and K-bands…
Variable dynamics in the inner disk of HD 135344B revealed with multi-epoch scattered light imaging
Tomas Stolker, Mike Sitko, Bernard Lazareff +12
We present multi-epoch VLT/SPHERE observations of the protoplanetary disk around HD 135344B (SAO 206462). The -band scattered light imagery reveal, with high spatial resolution…
Carbon Abundances in Starburst Galaxies of the Local Universe
Maria A. Peña-Guerrero, Claus Leitherer, Selma de Mink +2
The cosmological origin of carbon, the fourth most abundant element in the Universe, is not well known and matter of heavy debate. We investigate the behavior of C/O to O/H in orde…
3xmm j181923.7170616: an x-ray binary with a 408s pulsar
Hao Qiu, Ping Zhou, Wenfei Yu +2
We carry out a dedicated study of 3XMM J181923.7170616\ with an approximate pulsation period of 400~s using the XMM-Newton and Swift observations spanning across nine years. We…
Ca II 8542 Å brightenings induced by a solar microflare
C. Kuckein, A. Diercke, S. J. González Manrique +6
We study small-scale brightenings in Ca II 8542 Å line-core images to determine their nature and effect on localized heating and mass transfer in active regions. High-resolution 2D…
Photometric study of fourteen low-mass binaries
David Korda, Petr Zasche, Marek Wolf +3
New CCD photometric observations of fourteen short-period low-mass eclipsing binaries (LMB) in the photometric filters I, R and V were used for the light curve analysis. There stil…
Transmission spectroscopy of the hot Jupiter TrES-3 b: Disproof of an overly large Rayleigh-like feature
F. Mackebrandt, M. Mallonn, J. M. Ohlert +9
Context. Transit events of extrasolar planets offer the opportunity to study the composition of their atmospheres. Previous work on transmission spectroscopy of the close-in gas gi…
Generation mechanisms of quasi-parallel and quasi-circular flare ribbons in a confined flare
Aaron Hernandez-Perez, Julia K. Thalmann, Astrid M. Veronig +3
We analyze a confined multiple-ribbon M2.1 flare (SOL2015-01-29T11:42) that originated from a fan-spine coronal magnetic field configuration, within active region NOAA 12268. The o…
A Combinatorial Grassmannian Representation of the Magic Three-Qubit Veldkamp Line
Metod Saniga
It is demonstrated that the magic three-qubit Veldkamp line occurs naturally within the Veldkamp space of combinatorial Grassmannian of type , . The li…
Short Gamma-Ray Bursts following mergers of an ONeMg with a CO white dwarf
Maxim Lyutikov, Silvia Toonen
We discuss a scenario of short Gamma-Ray Bursts (GRBs) following a merger of a massive ONeMg white dwarf (WD) with a CO WD, and an ensuing accretion induced collapse (AIC). An init…
Neutrinos from beta processes in a presupernova: probing the isotopic evolution of a massive star
Kelly M. Patton, Cecilia Lunardini, Robert J. Farmer +1
We present a new calculation of the neutrino flux received at Earth from a massive star in the hours of evolution prior to its explosion as a supernova (presupernova). Us…
An unusual white dwarf star may be a surviving remnant of a subluminous Type Ia supernova
S. Vennes, P. Nemeth, A. Kawka +4
Subluminous Type Ia supernovae, such as the Type Iax class prototype SN 2002cx, are described by a variety of models such as the failed detonation and partial deflagration of an ac…
