Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae. X: The Tenth Year (2017)
Taichi Kato, Keisuke Isogai, Yasuyuki Wakamatsu +67
Continuing the project described by Kato et al. (2009, PASJ, 61, S395, arXiv/0905.1757), we collected times of superhump maxima for 102 SU UMa-type dwarf novae observed mainly duri…
Cloud model inversions of strong chromospheric absorption lines using principal component analysis
Ekaterina Dineva, Meetu Verma, Sergio Javier González Manrique +2
High-resolution spectroscopy of strong chromospheric absorption lines delivers nowadays several millions of spectra per observing day, when using fast scanning devices to cover lar…
Coordinated observations between China and Europe to follow active region 12709
S. J. González Manrique, C. Kuckein, P. Gömöry +5
We present the first images of a coordinated campaign to follow active region NOAA 12709 on 2018 May 13 as part of a joint effort between three observatories (China-Europe). The ac…
Drifting Pulsation Structure at the Very Beginning of the 2017 September 10 Limb Flare
M. Karlicky, B. Chen, D. E. Gary +2
Drifting pulsation structures (DPSs) are important radio fine structures usually observed at the beginning of eruptive solar flares. It has been suggested that DPSs carry important…
Science Requirement Document (SRD) for the European Solar Telescope (EST) (3rd Edition, December 2025)
Rolf Schlichenmaier, Luis R. Bellot Rubio, Manuel Collados Vera +31
The European Strategy Forum on Research Infrastructures (ESFRI) included the European Solar Telescope (EST) as an ESFRI Project in its 2016 Roadmap and confirmed this status in 202…
A wide star-black-hole binary system from radial-velocity measurements
Jifeng Liu, Haotong Zhang, Andrew W. Howard +52
All stellar mass black holes have hitherto been identified by X-rays emitted by gas that is accreting onto the black hole from a companion star. These systems are all binaries with…
HST/COS Spectra of the Wind Lines of VFTS 102 and 285
Katherine Shepard, Douglas R. Gies, Kathryn V. Lester +5
Rapid rotation in massive stars imposes a latitudinal variation in the mass loss from radiatively driven winds that can lead to enhanced mass loss at the poles (with little angular…
Mind the gap: The location of the lower edge of the pair instability supernovae black hole mass gap
R. Farmer, M. Renzo, S. E de Mink +2
Gravitational-wave detections are now starting to probe the mass distribution of stellar-mass black holes (BHs). Robust predictions from stellar models are needed to interpret thes…
2D non-LTE modelling of a filament observed in the H_alpha line with the DST/IBIS spectropolarimeter
P. Schwartz, S. Gunar, J. M. Jenkins +3
We study a fragment of a large quiescent filament observed on May 29, 2017 by the Interferometric BIdimensional Spectropolarimeter (IBIS) mounted at the Dunn Solar Telescope. We fo…
Spectral diagnostics of cool flare loops observed by SST: I. Inversion of the Ca II 8542 Å and H lines
Július Koza, David Kuridze, Petr Heinzel +3
Flare loops form an integral part of eruptive events, being detected in the range of temperatures from X-rays down to cool chromospheric-like plasmas. While the hot loops are routi…
Observations of a Footpoint Drift of an Erupting Flux Rope
Alena Zemanova, Jaroslav Dudik, Guillaume Aulanier +2
We analyze the imaging observations of an M-class eruptive flare of 2015 November, 4. The pre-eruptive H alpha filament was modelled by the non-linear force free field model, which…
HD 99458: First time ever Ap-type star as a Scuti pulsator in a short period eclipsing binary?
M. Skarka, P. Kabáth, E. Paunzen +18
We present the discovery of a unique object, a chemically peculiar Ap-type star showing Scuti pulsations which is bound in an eclipsing binary system with an orbital period sho…
Spectroscopy and Differential Emission Measure diagnostics of a coronal dimming associated with a fast halo CME
Astrid M. Veronig, Peter Gömöry, Karin Dissauer +2
We study the coronal dimming caused by the fast halo CME (deprojected speed v =1250 km s associated with the C3.7 two-ribbon flare on 2012 September 27, using Hinode/EIS s…
A massive white-dwarf merger product before final collapse
V. V. Gvaramadze, G. Gräfener, N. Langer +4
Gravitational wave emission can lead to the coalescence of close pairs of compact objects orbiting each other. For the case of neutron stars such mergers may yield masses above the…
Supernova 2018aoq and a distance to Seyfert galaxy NGC 4151
D. Yu. Tsvetkov, P. V. Baklanov, M. Sh. Potashov +9
We present optical photometric observations of SN 2018aoq from 2 to 100 days after explosion, and 7 spectra at epochs from 11 to 71 days. The light curves and spectra are typical f…
A revisit to the enigmatic variable star 21 Comae
Ernst Paunzen, Gerald Handler, Przemyslaw Walczak +12
The magnetic chemically peculiar (Ap/CP2) star 21 Com has been extensively studied in the past, albeit with widely differing and sometimes contradictory results, in particular conc…
Pre-eruption processes: heating, particle acceleration and the formation of a hot channel before the 2012 October 20 M9.0 limb flare
Aaron Hernandez-Perez, Yang Su, Astrid M. Veronig +3
We report a detailed study of the pre-eruption activities that led to the occurrence of an M9.0 flare/CME event on 2012 October 20 in NOAA AR 11598. This includes the study of the…
Mapping the magnetic field of flare coronal loops
D. Kuridze, M. Mathioudakis, H. Morgan +9
Here we report on the unique observation of flaring coronal loops at the solar limb using high resolution imaging spectropolarimetry from the Swedish 1-meter Solar Telescope. The v…
Apsidal Motion and Absolute Parameters of 21 Early-type Small Magellanic Cloud Eccentric Eclipsing Binaries
P. Zasche, M. Wolf
We present the apsidal motion and light-curve analyses of 21 eccentric eclipsing binaries located in the Small Magellanic Cloud. Most of these systems have never been studied befor…
