A Catalog of Automatically Identified Multi-Signature ICMEs Observed by Solar Orbiter
Felix N. Minta, Stefano A. Livi, George C. Ho +2
In this study, we present a catalog of 138 interplanetary coronal mass ejections (ICMEs) identified using multiple distance-normalized ICME criteria within sliding time windows app…
The Non-Eruptive Reconfiguration of a Quiescent Filament After a Nearby Active Region Emergence
James McKevitt, Louise Harra, Gherardo Valori +13
The unpredictability of solar filament eruptions presents major challenges for forecasting space weather, as such eruptions frequently drive coronal mass ejections (CMEs) that impa…
Alfvénic solar wind intervals observed by Solar Orbiter: Exploiting the capability of the SWA plasma suite and source region investigation
R. D'Amicis, J. M. Raines, S. Benella +32
Fast and slow solar wind have distinct properties linked to their solar sources.Alfvénic slow wind complicates the usual speed-based classification, especially at intermediate spe…
Proton specific entropy as a proxy for the charge state ratio over heliocentric distance
Jack D. Collard, Tamar Ervin, Ryan M. Dewey +10
While the fast solar wind has well-established origins in coronal holes, the source of the slow solar wind remains uncertain. Compositional metrics, such as heavy ion charge state…
Observational Constraints on the Radial Evolution of O Temperature and Differential Flow in the Inner Heliosphere
Yeimy J. Rivera, Kristopher G. Klein, Joseph H. Wang +15
Over decades of solar wind observations, heavy ions have been observed to have a higher temperature and flow faster than protons in the solar corona and heliosphere. Remote observa…
The Evolution of Heavy Ion Abundances with Solar Activity
B. L. Alterman, Y. J. Rivera, S. T. Lepri +2
When observed at 1 AU, slow solar wind is typically considered to have originated in source regions with magnetic topologies that are intermittently open to the heliosphere. Fast w…
