An application of the weighted horizontal magnetic gradient to solar compact and eruptive events
M. B. Korsos, Michael S. Ruderman, R. Erdelyi
We propose to apply the weighted horizontal magnetic gradient (), introduced in Korsos et al (2015), for analysing the pre-flare and pre-CME behaviour and evolution of Acti…
A new compact young moving group around V1062 Sco
Siegfried Röser, Elena Schilbach, Bertrand Goldman +3
Aims. We are searching for new open clusters or moving groups in the Solar neighbourhood. Methods. We used the Gaia-TGAS catalogue, cut it into narrow proper motion and parallax sl…
A Photometric Study of Globular Clusters Observed by the APOGEE Survey
Szabolcs Mészáros, D. A. García-Hernández, Santi Cassisi +8
In this paper we describe the photometric and spectroscopic properties of multiple populations in seven northern globular clusters. In this study we employ precise ground based pho…
An UXor among FUors: extinction related brightness variations of the young eruptive star V582 Aur
P. Ábrahám, Á. Kóspál, M. Kun +24
V582 Aur is an FU Ori-type young eruptive star in outburst since 1985. The eruption is currently in a relatively constant plateau phase, with photometric and spectroscopic va…
A view of the H-band light-element chemical patterns in Globular Clusters under the AGB self-enrichment scenario
F. Dell'Agli, D. A. García-Hernández, P. Ventura +7
We discuss the self-enrichment scenario by AGB stars for the formation of multiple populations in globular clusters (GCs) by analyzing data set of giant stars observed in 9 Galacti…
The Effect of "Rogue" Active Regions on the Solar Cycle
Melinda Nagy, Alexandre Lemerle, François Labonville +2
The origin of cycle-to-cycle variations in solar activity is currently the focus of much interest. It has recently been pointed out that large individual active regions with atypic…
12C/13C isotopic ratios in red-giant stars of the open cluster NGC 6791
László Szigeti, Szabolcs Mészáros, Verne V. Smith +10
Carbon isotope ratios, along with carbon and nitrogen abundances, are derived in a sample of 11 red-giant members of one of the most metal-rich clusters in the Milky Way, NGC 6791.…
Dissipative instabilities in a partially ionised prominence plasma slab: II. The effect of compressibility
J. F. Mather, I. Ballai, R. Erdelyi
This present study deals with the dissipative instability that appears in a compressible partially ionised plasma slab embedded in a uniform magnetic field, modelling the state of…
Observations of Running Penumbral Waves emerging in a Sunspot
T. G. Priya, Wenda Cao, Jiangtao Su +4
We present results from the investigation of 5-min umbral oscillations in a single-polarity sunspot of active region NOAA 12132. The spectra of TiO, H, and 304 Å are used for co…
Untwisting Jets Related to Magnetic Flux Cancellation
Jiajia Liu, Robert Erdélyi, Yuming Wang +1
The rotational motion of solar jets is believed to be a signature of the untwisting process resulting from magnetic reconnection, which takes place between twisted closed magnetic…
Predicting the Loci of Solar Eruptions
N. Gyenge, R. Erdélyi
The longitudinal distribution of solar active regions shows non-homogeneous spatial behaviour, which is often referred to as Active Longitude (AL). Evidence for a significant stati…
Rotation--differential rotation relationships for late-type single and binary stars from Doppler imaging
Zs. Kővári, K. Oláh, L. Kriskovics +3
From our sample of spotted late-type stars showing surface differential rotation we find that the relationship between the rotation period and the surface shear coefficient $α=ΔΩ/Ω…
Interferometric view of the circumstellar envelopes of northern FU Orionis-type stars
O. Fehér, Á. Kóspál, P. Ábrahám +2
FU Orionis-type objects are young, low-mass stars with large outbursts in visible light that last for several years or decades. They are thought to represent an evolutionary phase…
The Frequency-dependent Damping of Slow Magnetoacoustic Waves in a Sunspot Umbral Atmosphere
S. Krishna Prasad, D. B. Jess, T. Van Doorsselaere +5
High spatial and temporal resolution images of a sunspot, obtained simultaneously in multiple optical and UV wavelengths, are employed to study the propagation and damping characte…
Antisolar differential rotation with surface lithium enrichment on the single K-giant V1192 Orionis
Zs. Kővári, K. G. Strassmeier, T. A. Carroll +7
Context: Stars with about 12 solar masses at the red giant branch (RGB) represent an intriguing period of stellar evolution, i.e. when the convective envelope interacts with the…
Large amplitude change in spot-induced rotational modulation of the Kepler Ap star KIC 2569073
Jason A. Drury, Simon J. Murphy, Aliz Derekas +9
An investigation of the 200 200 pixel 'superstamp' images of the centres of the open clusters NGC 6791 and NGC 6819 allows for the identification and study of many variabl…
IRIS Burst Spectra Co-Spatial To A Quiet-Sun Ellerman-Like Brightening
C. J. Nelson, N. Freij, A. Reid +3
Ellerman bombs (EBs) have been widely studied over the past two decades; however, only recently have counterparts of these events been observed in the quiet-Sun. The aim of this ar…
