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…
Sunward Streaming 3He-rich SEP Events Observed by Solar Orbiter and Parker Solar Probe during Perihelion Passage
Samuel T. Hart, George C. Ho, Michael R. Terres +7
We report on two 3He-rich solar energetic particle (SEP) events observed by Solar Orbiter (SO) and Parker Solar Probe (PSP) during the April 1 - 4, 2024 conjunction when both space…
Recovering Ion Distribution Functions: II. Gyrotropic Slepian Reconstruction of Solar Wind Electrostatic Analyzer Measurements
Srijan Bharati Das, Michael Terres
Velocity distribution functions (VDF) are an essential observable for studying kinetic and wave-particle processes in solar wind plasmas. To experimentally distinguish modes of hea…
Recovering Ion Distribution Functions: I. Slepian Reconstruction of VDFs from MMS and Solar Orbiter
Srijan Bharati Das, Michael Terres
Plasma velocity distribution functions (VDFs) constitute a fundamental observation of numerous operational and future missions. An efficient parameterization of VDFs is crucial for…
