Signs of Sulphur fractionation under high magnetic field strength
Dominik Orlovskij, Andy S. H. To, David M. Long
Sulphur, with a first ionisation potential (FIP) of 10.36 eV, lies at the boundary between low- and high-FIP elements, making it particularly sensitive to fractionation processes i…
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…
Comparing First Ionisation Potential bias diagnostics in the solar atmosphere
Kristena D. Spruksta, David M. Long, Andy S. H. To
Plasma composition in the solar atmosphere differs between the photosphere and corona, producing an observable difference in elemental abundance known as the FIP effect. The FIP ef…
Probing the properties of active regions in the solar interface region using full-disk spectroheliograms
Ãabha 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…
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…
Investigating Solar Wind Outflows from Open-Closed Magnetic Field Structures Using Coordinated Solar Orbiter and Hinode Observations
Nawin Ngampoopun, Roberto Susino, David H. Brooks +13
ESA/NASA's Solar Orbiter (SO) allows us to study the solar corona at closer distances and from different perspectives, which helps us to gain significant insights into the origins…
