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…
On the Propagation and Damping of Alfvenic Fluctuations in the Outer Solar Corona and Solar Wind
Nikos Sioulas, Marco Velli, Chen Shi +17
We analyze \textit{Parker Solar Probe} and \textit{Solar Orbiter} observations to investigate the propagation and dissipation of Alfvénic fluctuations from the outer corona to 1~AU…
The impact of Alfvenic shear flow on magnetic reconnection and turbulence
Tamar Ervin, Alfred Mallet, Stefan Eriksson +9
Magnetic reconnection is a fundamental and omnipresent energy conversion process in plasma physics. Novel observations of fields and particles from Parker Solar Probe (PSP) have sh…
Multi-spacecraft Measurements of the Evolving Geometry of the Solar Alfvén Surface Over Half a Solar Cycle
Samuel T. Badman, Michael L. Stevens, Stuart D. Bale +18
The geometry of a star's Alfvén surface determines stellar angular momentum loss, separates a causally distinct 'corona' and stellar wind, and potentially affects exoplanetary habi…
Observational Constraints on the Radial Evolution of O Temperature and Differential Flow in the Inner Heliosphere
Yeimy J. Rivera, Kristopher G. Klein, Joseph H. Wang +15
Over decades of solar wind observations, heavy ions have been observed to have a higher temperature and flow faster than protons in the solar corona and heliosphere. Remote observa…
Frequency Dispersed Ion Acoustic Waves in the Near Sun Solar Wind: Signatures of Impulsive Ion Beams
David M. Malaspina, Robert E. Ergun, Iver H. Cairns +4
This work reports a novel plasma wave observation in the near-Sun solar wind: frequency-dispersed ion acoustic waves. Similar waves were previously reported in association with int…
