Conversion Layer Controls the Evolution of Magnetic Deflections Near the Alfven Surface
Dominic Payne, Mojtaba Akhavan-Tafti, Joshua Goodwill +10
We examine the statistics of Alfvenic deflections in both sub-Alfvenic and super-Alfvenic solar wind with particular focus on a common parameter that underlies the definition of sw…

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…

Characterization of the Trans-Alfvénic Region Using Observations from Parker Solar Probe
Subash Adhikari, Riddhi Bandyopadhyay, Joshua Goodwill +14
Close to Earth the solar wind is usually super-Alfvénic, i.e. the speed of the solar wind is much larger than the Alfvén speed. However, in the lower coronal regions, the solar win…
