Energy and mass transport associated with impulsive spicular flows in solar coronal holes
Lei Ni, Jun Lin, Tanmoy Samanta +3
How the solar atmosphere is heated from a temperature of about \,K in the lower atmosphere to about \,MK in the corona has challenged the astrophysical community…

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…
Magnetic Rayleigh-Taylor Instability at a Contact Discontinuity With Oblique Magnetic Field
E. Vickers, I. Ballai, R. Erdélyi
Aims: In the present work we investigate the nature of the magnetic Rayleigh-Taylor instability at a density interface permeated by an oblique, homogeneous magnetic field in an inc…
Varying Driver Velocity Fields in Photospheric MHD Wave Simulations
A. J. Leonard, S. J. Mumford, V. Fedun +1
Torsional motions are ubiquitous in the solar atmosphere. In this work, we perform 3D numerical simulations which mimic a vortex-type photospheric driver with a Gaussian spatial pr…
Magnetic shocks and substructures excited by torsional Alfvén wave interactions in merging expanding flux tubes
B. Snow, V. Fedun, F. A. Gent +2
Vortex motions are frequently observed on the solar photosphere. These motions may play a key role in the transport of energy and momentum from the lower atmosphere into the upper…
On the evolution of pre-flare patterns of a 3-dimensional model of AR 11429
M. B. Korsos, S. Poedts, N. Gyenge +6
We apply a novel pre-flare tracking of sunspot groups towards improving the estimation of flare onset time by focusing on the evolution of the 3D magnetic field construction of AR…
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…
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…
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…
An Inside Look at Sunspot Oscillations with Higher Azimuthal Wavenumbers
David B. Jess, Tom Van Doorsselaere, Gary Verth +7
Solar chromospheric observations of sunspot umbrae offer an exceptional view of magneto-hydrodynamic wave phenomena. In recent years, a wealth of wave signatures related to propaga…
