The Contribution of Alpha Particles to the Solar Wind Angular Momentum Flux in the Inner Heliosphere

Adam J. Finley, Michael D. McManus, Sean P. Matt +14

An accurate assessment of the Sun's angular momentum (AM) loss rate is an independent constraint for models that describe the rotation evolution of Sun-like stars. In-situ measurem…

Wave-particle energy transfer directly observed in an ion cyclotron wave

Daniel Vech, Mihailo M. Martinovic, Kristopher G. Klein +21

Context. The first studies with Parker Solar Probe (PSP) data have made significant progress toward the understanding of the fundamental properties of ion cyclotron waves in the in…

Electron heat flux in the near-Sun environment

J. S. Halekas, P. L. Whittlesey, D. E. Larson +15

We survey the electron heat flux observed by the Parker Solar Probe (PSP) in the near-Sun environment at heliocentric distances of 0.125-0.25 AU. We utilized measurements from the…

Detection of small magnetic flux ropes from the third and fourth Parker Solar Probe encounters

L. -L. Zhao, G. P. Zank, Q. Hu +22

We systematically search for magnetic flux rope structures in the solar wind to within the closest distance to the Sun of 0.13 AU, using data from the third and fourth orbits of th…

The Solar Wind Angular Momentum Flux as Observed by Parker Solar Probe

Adam J. Finley, Sean P. Matt, Victor Réville +9

The long-term evolution of the Sun's rotation period cannot be directly observed, and is instead inferred from trends in the measured rotation periods of other Sun-like stars. Assu…

Small-scale Magnetic Flux Ropes in the First two Parker Solar Probe Encounters

Yu Chen, Qiang Hu, Lingling Zhao +15

Small-scale magnetic flux ropes (SFRs) are a type of structures in the solar wind that possess helical magnetic field lines. In a recent report (Chen & Hu 2020), we presented the r…

The Temperature Anisotropy and Helium Abundance Features of Alfvénic Slow Solar Wind Observed by Parker Solar Probe, Helios, and Wind Missions

Jia Huang, Davin E. Larson, Tamar Ervin +20

Slow solar wind is typically characterized as having low Alfvénicity, but the occasional occurrence of highly Alfvénic slow solar wind (HASSW) raises questions about its source reg…

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…

Coronal Electron Temperature inferred from the Strahl Electrons in the Inner Heliosphere: Parker Solar Probe and Helios observations

Laura Bercic, Davin Larson, Phyllis Whittlesey +17

The shape of the electron velocity distribution function plays an important role in the dynamics of the solar wind acceleration. Electrons are normally modelled with three componen…

Sunward propagating whistler waves collocated with localized magnetic field holes in the solar wind: Parker Solar Probe observations at 35.7 Sun radii

O. V. Agapitov, T. Dudok de Wit, F. S. Mozer +21

Observations by the Parker Solar Probe mission of the solar wind at about 35.7 solar radii reveal the existence of whistler wave packets with frequencies below 0.1 f/fce (20-80 Hz…

The Solar Probe ANalyzers -- Electrons on Parker Solar Probe

Phyllis L Whittlesey, Davin E Larson, Justin C Kasper +19

Electrostatic analyzers of different designs have been used since the earliest days of the space age, beginning with the very earliest solar wind measurements made by Mariner 2 en…

The Radial Dependence of Proton-scale Magnetic Spectral Break in Slow Solar Wind during PSP Encounter 2

Die Duan, Trevor A. Bowen, Christopher H. K. Chen +18

Magnetic field fluctuations in the solar wind are commonly observed to follow a power law spectrum. Near proton-kinetic scales, a spectral break occurs which is commonly interprete…

Parker Solar Probe In-Situ Observations of Magnetic Reconnection Exhausts During Encounter 1

T. D. Phan, S. D. Bale, J. P. Eastwood +23

Magnetic reconnection in current sheets converts magnetic energy into particle energy. The process may play an important role in the acceleration and heating of the solar wind clos…

Inner-Heliosphere Signatures of Ion-Scale Dissipation and Nonlinear Interaction

Trevor A. Bowen, Alfred Mallet, Stuart D. Bale +19

We perform a statistical study of the turbulent power spectrum at inertial and kinetic scales observed during the first perihelion encounter of Parker Solar Probe. We find that oft…

Density Fluctuations in the Solar Wind Based on Type III Radio Bursts Observed by Parker Solar Probe

Vratislav Krupar, Adam Szabo, Milan Maksimovic +20

Radio waves are strongly scattered in the solar wind, so that their apparent sources seem to be considerably larger and shifted than the actual ones. Since the scattering depends o…

Relating streamer flows to density and magnetic structures at the Parker Solar Probe

Alexis P. Rouillard, Athanasios Kouloumvakos, Angelos Vourlidas +34

The physical mechanisms that produce the slow solar wind are still highly debated. Parker Solar Probe's (PSP's) second solar encounter provided a new opportunity to relate in situ…
