Encounter of Parker Solar Probe and a Comet-like Object During Their Perihelia: Model Predictions and Measurements
Jiansen He, Bo Cui, Liping Yang +15
Parker Solar Probe (PSP) aims at exploring the nascent solar wind close to the Sun. Meanwhile, PSP is also expected to encounter small objects like comets and asteroids. In this wo…
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…
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…
Measurement of the Open Magnetic Flux in the Inner Heliosphere down to 0.13AU
Samuel T. Badman, Stuart D. Bale, Alexis P. Rouillard +7
(Abridged) Aim: We attempt to determine robust estimates of the heliospheric magnetic flux () using Parker Solar Probe (PSP) data, analyze how susceptible this is to overestim…
Narrowband oblique whistler-mode waves: Comparing properties observed by Parker Solar Probe at <0.2 AU and STEREO at 1 AU
C. Cattell, B. Short, A. Breneman +15
AIM: Large amplitude narrowband obliquely propagating whistler-mode waves at frequencies of ~0.2 fce (electron cyclotron frequency) are commonly observed at 1 AU, and are most cons…
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…
Dust impact voltage signatures on Parker Solar Probe: influence of spacecraft floating potential
S. D. Bale, K. Goetz, J. W. Bonnell +15
When a fast dust particle hits a spacecraft, it generates a cloud of plasma some of which escapes into space and the momentary charge imbalance perturbs the spacecraft voltage with…
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…
Localized magnetic field structures and their boundaries in the near-Sun solar wind from Parker Solar Probe measurements
V. Krasnoselskikh, A. Larosa, O. Agapitov +18
One of the discoveries made by Parker Solar Probe during first encounters with the Sun is the ubiquitous presence of relatively small-scale structures standing out as sudden deflec…
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 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…
A Merged Search-Coil and Fluxgate Magnetometer Data Product for Parker Solar Probe FIELDS
Trevor A. Bowen, Stuart D. Bale, John W. Bonnell +12
NASA's Parker Solar Probe (PSP) mission is currently investigating the local plasma environment of the inner-heliosphere (0.25) using both {\em{in-situ}} and remote se…
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…
