Elemental Composition Evolution during the 2024 September 30 Solar Eruption: A Comparison of Hot and Cool Plasma Components with Solar Orbiter/SPICE, Hinode/EIS, and Chandrayaan-2/XSM
Momchil Molnar, Joseph Plowman, Amir Caspi +7
Solar plasma composition differs between the photosphere and corona over a range of timescales, with preferential enhancement of elements with low first ionization potential (FIP).…
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…
Coronal hole picoflare jets are progenitors of both fast and Alfvénic slow solar wind
L. P. Chitta, Z. Huang, R. D'Amicis +19
Solar wind, classified by its bulk speed and the Alfvénic nature of its fluctuations, generates the heliosphere. The elusive physical processes responsible for the generation of t…
A New Method of Deriving Doppler Velocities for Solar Orbiter SPICE
J. E. Plowman, D. M. Hassler, M. E. Molnar +7
This paper presents a follow-up to previous work on correcting PSF-induced Doppler artifacts in observations by the SPICE spectrograph on Solar Orbiter. In a previous paper, we dem…
