Evidence of energy conversion in weakly collisional plasma during an interplanetary coronal mass ejection
Omkar Dhamane, Anil Raghav, Simone Benella +14
Intervals of enhanced turbulent fluctuations are typically less frequent within the magnetic cloud region of an interplanetary coronal mass ejection (ICME). We investigate two such…
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…
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…
On the Regulation of the Solar Wind Helium Abundance by the Hydrogen Compressibility
B. L. Alterman, R. D'Amicis
Traditionally, fast solar wind is considered to originate in solar source regions that are continuously open to the heliosphere and slow wind originates in regions that are intermi…
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…
Cross Helicity and the Helium Abundance as an in situ Metric of Solar Wind Acceleration
B. L. Alterman, R. D'Amicis
The two-state solar wind paradigm is based on observations showing that slow and fast solar wind have distinct properties like helium abundances, kinetic signatures, elemental comp…
