Switchbacks: statistical properties and deviations from alfvénicity

A. Larosa, V. Krasnoselskikh, T. Dudok de Witınst +16

{Parker Solar Probe's first solar encounter has revealed the presence of sudden magnetic field deflections that are called switchbacks and are associated with proton velocity enhan…

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 Orbiter Science Activity Plan: translating solar and heliospheric physics questions into action

I. Zouganelis, A. De Groof, A. P. Walsh +182

Solar Orbiter is the first space mission observing the solar plasma both in situ and remotely, from a close distance, in and out of the ecliptic. The ultimate goal is to understand…

High-resolution observations of the solar photosphere, chromosphere and transition region. A database of coordinated IRIS and SST observations

L. H. M. Rouppe van der Voort, B. De Pontieu, M. Carlsson +30

NASA's Interface Region Imaging Spectrograph (IRIS) provides high resolution observations of the solar atmosphere through UV spectroscopy and imaging. Since the launch of IRIS in J…

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…

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…
