Properties of Magnetic Switchbacks in the Near-Sun Solar Wind
Samuel T. Badman, Naïs Fargette, Lorenzo Matteini +24
Magnetic switchbacks are fluctuations in the solar wind in which the interplanetary magnetic field sharply deflects away from its background direction so as to create folds in magn…
In situ Evidence of 5-minute Oscillations from Parker Solar Probe
Zesen Huang, Marco Velli, Olga Panasenco +19
The Sun's surface vibrates in characteristic 5-minute oscillations, known as p-modes, generated by sound waves trapped within the convection zone. Although these oscillations have…

Electron Beam Propagation and Radio-Wave Scattering in the Inner Heliosphere using Five Spacecraft
Luis Alberto Cañizares, Sam T. Badman, Nicolina Chrysaphi +4
Solar energetic particles such as electrons can be accelerated to mildly-relativistic velocities in the solar corona. These electrons travel through the turbulent corona generating…
Differentiating the acceleration mechanisms in the slow and Alfvénic slow solar wind
Yeimy J. Rivera, Samuel T. Badman, J. L. Verniero +18
In the corona, plasma is accelerated to hundreds of kilometers per second, and heated to temperatures hundreds of times hotter than the Sun's surface, before it escapes to form the…
Characteristics and Source Regions of Slow Alfvenic Solar Wind Observed by Parker Solar Probe

Using a classification scheme for solar wind type based on the heliocentric distance of the observation, we look at near perihelion observations from Parker Solar Probe Encounters…
Near subsonic solar wind outflow from an active region
Tamar Ervin, Stuart D. Bale, Samuel T. Badman +10
During Parker Solar Probe (Parker) Encounter 15 (E15), we observe an 18-hour period of near subsonic ( 1) and sub-Alfvénic (SA), <<< 1, slow speed…
Tracking solar radio bursts using Bayesian multilateration
L. A. Cañizares, S. T. Badman, S. A. Maloney +4
Solar radio bursts (SRBs), are emitted by electrons propagating through the corona and interplanetary space. Tracking such bursts is key to understanding the properties of accelera…
Compositional metrics of fast and slow Alfvenic solar wind emerging from coronal holes and their boundaries
Tamar Ervin, Stuart D. Bale, Samuel T. Badman +7
We seek to understand the composition and variability of fast (FSW) and slow Alfvenic solar wind (SASW) emerging from coronal holes (CH). We leverage an opportune conjunction betwe…
The Temperature, Electron, and Pressure Characteristics of Switchbacks: Parker Solar Probe Observations
