UK White Paper on Space-based total solar eclipse observations: structure and dynamics of the solar atmosphere
Lucie M. Green, Nicola Baresi, Huw Morgan +19
Our Sun is uniquely placed to enable a detailed study of astrophysical plasmas and how they are governed by the magnetic fields that thread through them. On the one hand, magnetic…
Hinode EIS Observations of Plasma Composition Evolution and Radiative Cooling of Solar Flare Loops
Teodora Mihailescu, Peter R. Young, David H. Brooks +4
Plasma composition in flaring regions has been shown to have significant spatial and temporal variations, likely driven by dynamical processes that take place as a consequence of t…
Probing the properties of active regions in the solar interface region using full-disk spectroheliograms
Éabha Power, David M. Long, Teodora Mihailescu +1
The composition of plasma in the solar corona is characterised by the First Ionisation Potential (FIP) bias, and is thought to be the result of a ponderomotive force acting in the…
Coronal Non-Thermal and Doppler Plasma Flows Driven by Photospheric Flux in 28 Active Regions
James McKevitt, Sarah Matthews, Deborah Baker +5
Magnetohydrodynamic (MHD) waves and/or the braiding of magnetic field lines are largely thought to be responsible for heating the solar corona, both being mechanisms which are driv…
Systematic non-thermal velocity increase preceding soft X-ray flare onset: A large-scale Hinode/EIS study
Andy S. H. To, Abigail Burden, Deborah Baker +12
Non-thermal velocities, derived from spectral line broadening, can provide crucial insights into plasma dynamics before and during solar flares. To systematically study the pre-fla…
Spectroscopic Observations of Supra-Arcade Downflows
Ryan J. French, Maria D. Kazachenko, Teodora Mihailescu +1
Despite their somewhat-frequent appearance in EUV imaging of off-limb flares, the origins of Supra-Arcade Downflows (SADs) remain a mystery. Appearing as dark, tendril-like downflo…
Searching for evidence of subchromospheric magnetic reconnection on the Sun
D. Baker, L. van Driel-Gesztelyi, A. W. James +13
Within the coronae of stars, abundances of those elements with low first ionization potential (FIP) often differ from their photospheric values. The coronae of the Sun and solar-ty…
Intriguing Plasma Composition Pattern in a Solar Active Region: a Result of Non-Resonant Alfvén Waves?
Teodora Mihailescu, David H. Brooks, J. Martin Laming +6
The plasma composition of the solar corona is different from that of the solar photosphere. Elements that have a low first ionisation potential (FIP) are preferentially transported…
Slow Solar Wind Connection Science during Solar Orbiter's First Close Perihelion Passage
Stephanie L. Yardley, Christopher J. Owen, David M. Long +76
The Slow Solar Wind Connection Solar Orbiter Observing Plan (Slow Wind SOOP) was developed to utilise the extensive suite of remote sensing and in situ instruments on board the ESA…
Observational Evidence of S-Web Source of the Slow Solar Wind
D. Baker, P. Demoulin, S. L. Yardley +25
From 2022 March 18-21, active region (AR) 12967 was tracked simultaneously by Solar Orbiter (SO) at 0.35 au and Hinode/EIS at Earth. During this period, strong blue-shifted plasma…
The magnetic field environment of active region 12673 that produced the energetic particle events of September 2017
Stephanie L. Yardley, Lucie M. Green, Alexander W. James +2
Forecasting solar energetic particles (SEPs), and identifying flare/CMEs from active regions (ARs) that will produce SEP events in advance is extremely challenging. We investigate…
What determines active region coronal plasma composition?
Teodora Mihailescu, Deborah Baker, Lucie M. Green +4
The chemical composition of the solar corona is different from that of the solar photosphere, with the strongest variation being observed in active regions (ARs). Using data from t…
Evolution of Plasma Composition in an Eruptive Flux Rope
Deborah Baker, Lucie M. Green, David H. Brooks +8
Magnetic flux ropes are bundles of twisted magnetic field enveloping a central axis. They harbor free magnetic energy and can be progenitors of coronal mass ejections (CMEs), but i…
Plasma Upflows Induced by Magnetic Reconnection Above an Eruptive Flux Rope
Deborah Baker, Teodora Mihailescu, Pascal Demoulin +6
One of the major discoveries of Hinode's Extreme-ultraviolet Imaging Spectrometer (EIS) is the presence of upflows at the edges of active regions. As active regions are magneticall…
First radiative shock experiments on the SG-II laser
Francisco Suzuki-Vidal, Thomas Clayson, Chantal Stehlé +17
We report on the design and first results from experiments looking at the formation of radiative shocks on the Shenguang-II (SG-II) laser at the Shanghai Institute of Optics and Fi…
Spatial variations of low mass negative ions in Titan's upper atmosphere
Teodora Mihailescu, Ravindra Desai, Oleg Shebanits +5
Observations with Cassini's Electron Spectrometer discovered negative ions in Titan's ionosphere, at altitudes between 1400 and 950 km. Within the broad mass distribution extending…
