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…
FOXSI-2 Solar Microflares II: Hard X-ray Imaging Spectroscopy and Flare Energetics
Juliana T. Vievering, Lindsay Glesener, P. S. Athiray +7
We study the nature of energy release and transfer for two sub-A class solar microflares observed during the second flight of the Focusing Optics X-ray Solar Imager (FOXSI-2) sound…
Enhanced proton parallel temperature inside patches of switchbacks in the inner heliosphere
L. D. Woodham, T. S. Horbury, L. Matteini +16
Switchbacks are discrete angular deflections in the solar wind magnetic field that have been observed throughout the heliosphere. Recent observations by Parker Solar Probe (PSP) ha…
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…
Switchbacks as signatures of magnetic flux ropes generated by interchange reconnection in the corona
J. F. Drake, O. Agapitov, M. Swisdak +10
The structure of magnetic flux ropes injected into the solar wind during reconnection in the coronal atmosphere is explored with particle-in-cell simulations and compared with in s…
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…
Recurrent Solar Energetic Particle Flux Enhancements Observed near Earth and Mars
C. Krishnaprasad, Smitha V. Thampi, Anil Bhardwaj +3
August 1 to November 15, 2016 period was characterized by the presence of Corotating Interaction Regions (CIRs) and a few weak Coronal Mass Ejections (CMEs) in the heliosphere. In…
Coherent events at ion scales in the inner Heliosphere: \textit{Parker Solar Probe} observations during the first Encounter
Denise Perrone, Roberto Bruno, Raffaella D'Amicis +7
\textit{Parker Solar Probe} has shown the ubiquitous presence of strong magnetic field deflections, namely switchbacks, during its first perihelion where it was embedded in a highl…
Periodicities in an active region correlated with Type III radio bursts observed by Parker Solar Probe
Cynthia Cattell, Lindsay Glesener, Benjamin Leiran +5
Context. Periodicities have frequently been reported across many wavelengths in the solar corona. Correlated periods of ~5 minutes, comparable to solar p-modes, are suggestive of c…
Sensitivity of solar wind mass flux to coronal temperature
D. Stansby, L. Berčič, L. Matteini +4
Solar wind models predict that the mass flux carried away from the Sun in the solar wind should be extremely sensitive to the temperature in the corona, where the solar wind is acc…
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…
Electron acceleration and radio emission following the early interaction of two coronal mass ejections
D. E. Morosan, E. Palmerio, J. E. Räsänen +6
Context. Coronal mass ejections (CMEs) are large eruptions of magnetised plasma from the Sun that are often accompanied by solar radio bursts produced by accelerated electrons. Aim…
Sun-as-a-star Spectral Irradiance Observations of Transiting Active Regions
Shin Toriumi, Vladimir S. Airapetian, Hugh S. Hudson +3
Major solar flares are prone to occur in active region atmospheres associated with large, complex, dynamically-evolving sunspots. This points to the importance of monitoring the ev…
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
