Spectroscopic He I 1083 nm prominence eruption observations in the middle corona with MLSO/UCoMP
Chloe Pistelli, Momchil E Molnar, Giuliana de Toma +1
Coronal mass ejections (CMEs) are a major driver of space weather as they propagate through the heliosphere. Many CMEs have associated prominence material entangled in their magnet…
Active region upflows in various coronal structures and their coupling to the lower atmosphere
Yingjie Zhu, Louise Harra, Krzysztof Barczynski +13
Plasma upflows with a Doppler shift exceeding -10 km/s at active region (AR) boundaries are considered potential sources of the nascent slow solar wind. We investigate the driving…
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…
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…
Observations of Fan-Spine Topology by Solar Orbiter/EUI: Rotational Motions and Indications of Alfvén Waves
E. Petrova, T. Van Doorsselaere, D. Berghmans +3
Torsional Alfvén waves do not produce any intensity variation and are, therefore, challenging to observe with imaging instruments. Previously, Alfvén wave observations were reporte…
High-fidelity 3D Reconstruction of Solar Coronal Physics with the Updated CROBAR Method
Joseph Plowman, Daniel B. Seaton, Amir Caspi +2
We present an extension of the Coronal Reconstruction Onto B-Aligned Regions (CROBAR) method to Linear Force Free Field (LFFF) extrapolations, and apply it to the reconstruction of…
