The connection between solar coronal abundances and the underlying lower atmospheric properties
Paola Testa, Juan Martinez-Sykora, Bart De Pontieu +4
Elemental abundances in the solar corona and solar wind are often observed to differ from those in the solar photosphere, most commonly showing an enhancement of low first ionizati…
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…
XRISM view of a stellar flare: High-resolution Fe K spectra of HR 1099, an RS CVn-type star
Miki Kurihara, Masahiro Tsujimoto, Michael Loewenstein +21
A high-resolution X-ray spectroscopic observation was made of the RS CVn-type binary star HR 1099 using the Resolve instrument onboard XRISM for its calibration purposes. During th…
Radiative hydrodynamic simulations of FIP fractionation in solar flares
Jeffrey W. Reep, Luke Fushimi Benavitz, Andy S. H. To +5
Elemental abundances in solar flares are observed to vary both spatially and temporally, but the underlying mechanisms remain poorly understood. There is an interplay between advec…
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…
