Exploring the Solar Wind from its Source on the Corona into the Inner Heliosphere during the First Solar Orbiter - Parker Solar Probe Quadrature
Daniele Telloni, Vincenzo Andretta, Ester Antonucci +68
This Letter addresses the first Solar Orbiter (SO) -- Parker Solar Probe (PSP) quadrature, occurring on January 18, 2021, to investigate the evolution of solar wind from the extend…
Evolution of switchbacks in the inner Heliosphere
Anna Tenerani, Nikos Sioulas, Lorenzo Matteini +3
We analyze magnetic field data from the first six encounters of PSP, three Helios fast streams and two Ulysses south polar passes covering heliocentric distances $0.1\lesssim R\les…
A solar source of Alfvénic magnetic field switchbacks: {\em in situ} remnants of magnetic funnels on supergranulation scales
S. D. Bale, T. S. Horbury, M. Velli +17
One of the striking observations from the Parker Solar Probe (PSP) spacecraft is the prevalence in the inner heliosphere of large amplitude, Alfvénic magnetic field reversals terme…
Alfvénic versus non-Alfvénic turbulence in the inner heliosphere as observed by Parker Solar Probe
Chen Shi, Marco Velli, Olga Panasenco +20
We make use of the Parker Solar Probe (PSP) data to explore the nature of solar wind turbulence focusing on the Alfvénic character and power spectra of the fluctuations and their d…
