Proton Core Behaviour Inside Magnetic Field Switchbacks
Thomas Woolley, Lorenzo Matteini, Timothy S. Horbury +10
During Parker Solar Probe's first two orbits there are widespread observations of rapid magnetic field reversals known as switchbacks. These switchbacks are extensively found in th…
Parker Solar Probe observations of proton beams simultaneous with ion-scale waves
J. L. Verniero, D. E. Larson, R. Livi +19
Parker Solar Probe (PSP), NASA's latest and closest mission to the Sun, is on a journey to investigate fundamental enigmas of the inner heliosphere. This paper reports initial obse…
Proton Temperature Anisotropy Variations in Inner Heliosphere Estimated with First Parker Solar Probe Observations
Jia Huang, Justin C. Kasper, Daniel Vech +27
We report proton temperature anisotropy variations in the inner heliosphere with Parker Solar Probe (PSP) observations. Using a linear fitting method, we derive proton temperature…
Helium Variation Across Two Solar Cycles Reveals A Speed-Dependent Phase Lag
B. L. Alterman, Justin C. Kasper
We study the relationship between solar wind helium to hydrogen abundance ratio (), solar wind speed (), and sunspot number (SSN) over solar cycles 23…
Parallel-propagating Fluctuations at Proton-kinetic Scales in the Solar Wind are Dominated by Kinetic Instabilities
Lloyd D. Woodham, Robert T. Wicks, Daniel Verscharen +3
We use magnetic helicity to characterise solar wind fluctuations at proton-kinetic scales from Wind observations. For the first time, we separate the contributions to helicity from…
A Majority of Solar Wind Intervals Support Ion-Driven Instabilities
K. G. Klein, B. A. Alterman, M. L. Stevens +2
We perform a statistical assessment of solar wind stability at 1 AU against ion sources of free energy using Nyquist's instability criterion. In contrast to typically employed thre…
