The active region source of a type III radio storm observed by Parker Solar Probe during Encounter 2

no code implementations9 Feb 2021 L. Harra, D. H. Brooks, S. D. Bale, C. H. Mandrini, K. Barczynski, R. Sharma, S. T. Badman, S. Vargas Dominguez, M. Pulupa

We demonstrate that although the active region on the disk produces no significant flares, its evolution indicates it is a source of the electron beams causing the radio storm.

Parker Solar Probe evidence for scattering of electrons in the young solar wind by narrowband whistler-mode waves

no code implementations13 Jan 2021 C. Cattell, A. Breneman, J. Dombeck, B. Short, J. Wygant, J. Halekas, Tony Case, J. Kasper, D. Larson, Mike Stevens, P. Whittesley, S. Bale T. Dudok de Wit, K. Goodrich, R. MacDowall, M. Moncuquet, D. Malaspina, M. Pulupa

A comparison of the wave power in the whistler-mode frequency band to pitch angle width and a measure of anisotropy provides additional evidence for the electron scattering by whistler-mode waves.

Solar wind energy flux observations in the inner heliosphere: First results from Parker Solar Probe

no code implementations8 Jan 2021 M. Liu, K. Issautier, N. Meyer-Vernet, M. Moncuquet, M. Maksimovic, J. S. Halekas, J. Huang, L. Griton, S. Bale, J. W. Bonnell, A. W. Case, K. Goetz, P. R. Harvey, J. C. Kasper, R. J. MacDowall, D. M. Malaspina, M. Pulupa, M. L. Stevens

We investigate the solar wind energy flux in the inner heliosphere using 12-day observations around each perihelion of Encounter One (E01), Two (E02), Four (E04), and Five (E05) of Parker Solar Probe (PSP), respectively, with a minimum heliocentric distance of 27. 8 solar radii ($R_\odot{}$).
