Evolution and Impact of Switchbacks Throughout the Heliosphere
Alfred Mallet, Chen Shi, Anna Tenerani +23
Magnetic switchbacks are large-amplitude fluctuations in the interplanetary magnetic field, and appear frequently in the near-Sun solar wind explored recently by Parker Solar Probe…
Strong Prevalence of Hammerhead Velocity Distributions Close to the Heliospheric Current Sheet
Srijan Bharati Das, Jaye L. Verniero, Samuel T. Badman +13
The solar wind undergoes non-adiabatic heating as it travels away from the Sun. The velocity phase space distribution of non-equilibrium ions in the solar wind indicate a source of…
Conversion Layer Controls the Evolution of Magnetic Deflections Near the Alfven Surface
Dominic Payne, Mojtaba Akhavan-Tafti, Joshua Goodwill +10
We examine the statistics of Alfvenic deflections in both sub-Alfvenic and super-Alfvenic solar wind with particular focus on a common parameter that underlies the definition of sw…
Tracing a Multi-Temperature Quiescent Prominence's Thermodynamic Evolution from Sun to Earth
Callie A. GarcÃa, Yeimy J. Rivera, Samuel T. Badman +5
Solar prominences are cool, dense stable structures routinely observed in the corona. Prominences are often ejected from the Sun via coronal mass ejections (CMEs). However, they ar…
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…
Bayesian and Deterministic Neural Network approaches to Faraday Cup calibration and plasma parameter estimation
Lidiya Ahmed, Michael L Stevens, Kristoff Paulson +2
We describe a novel scheme for analyzing particle detector measurements when a well-calibrated, similarly instrumented spacecraft is present in a similar orbit. To prepare ground t…
