Ejecta clumps revealed by study of reverse-shocked ejecta through MUSE integral field spectroscopy of SNR 0509-67.5
Priyam Das, Ivo Seitenzahl, J. Martin Laming +3
We report the discovery of a spatially resolved clumpy ejecta structure in the reverse-shocked ejecta of SNR 0509-67.5, revealed through multiple faint and broad forbidden coronal…
Chromospheric dynamics and turbulence regulate the solar FIP effect
Andy S. H. To, J. Martin Laming, Jeffrey Reep +1
Elemental abundance variations in the solar corona, commonly characterised by First Ionisation Potential (FIP) bias, provide crucial diagnostics of chromospheric processes. The pon…
Helium emission from Balmer-dominated shocks in Type Ia supernova remnants provides constraints to their progenitor systems
Priyam Das, Ivo Rolf Seitenzahl, Parviz Ghavamian +4
Balmer-dominated shocks in Type Ia supernova remnants offer powerful probes into collisionless shock physics and hints towards supernova progenitor environments. Prior studies focu…
FIP Bias Evolution in an Emerging Active Region as observed in SPICE Synoptic Observations
T. Varesano, D. M. Hassler, N. Zambrana Prado +6
We investigate the time evolution of relative elemental abundances in the context of the first ionization potential effect focusing on an active region. Our aim is to characterize…
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…
