Nature of Transonic Sub-Alfvénic Turbulence and Density Fluctuations in the Near-Sun Solar Wind: Insights from Magnetohydrodynamic Simulations and Nearly-Incompressible Models
Giuseppe Arrò, Hui Li, Gary P. Zank +2
Recent Parker Solar Probe measurements have revealed that solar wind (SW) turbulence transits from a subsonic to a transonic regime near the Sun, while remaining sub-Alfvénic. Thes…
Characterization of Turbulent Fluctuations in the Sub-Alfvenic Solar Wind
Gary P. Zank, Lingling Zhao, Laxman Adhikari +8
Parker Solar Probe (PSP) observed sub-Alfvenic solar wind intervals during encounters 8 - 14, and low-frequency magnetohydrodynamic turbulence in these regions may differ from that…
Coronal Heating Rate in the Slow Solar Wind
Daniele Telloni, Marco Romoli, Marco Velli +59
This Letter reports the first observational estimate of the heating rate in the slowly expanding solar corona. The analysis exploits the simultaneous remote and local observations…
Does Turbulence along the Coronal Current Sheet Drive Ion Cyclotron Waves?
Daniele Telloni, Gary P. Zank, Laxman Adhikari +32
Evidence for the presence of ion cyclotron waves, driven by turbulence, at the boundaries of the current sheet is reported in this paper. By exploiting the full potential of the jo…
Modeling of Joint Parker Solar Probe - Metis/Solar Orbiter Observations
Laxman Adhikari, Gary P. Zank, Daniele Telloni +1
We present a first theoretical modeling of joint Parker Solar Probe (PSP) - Metis/Solar Orbiter (SolO) quadrature observations Telloni et al 2022c. The combined observations descri…
Observation of Magnetic Switchback in the Solar Corona
Daniele Telloni, Gary P. Zank, Marco Stangalini +49
Switchbacks are sudden, large radial deflections of the solar wind magnetic field, widely revealed in interplanetary space by the Parker Solar Probe. The switchbacks' formation mec…
Turbulence in the Sub-Alfvénic Solar Wind
G. P. Zank, L. -L. Zhao, L. Adhikri +5
Parker Solar Probe (PSP) entered a region of the sub-Alfvenic solar wind during encounter 8 and we present the first detailed analysis of low-frequency turbulence properties in thi…
Inertial range magnetic fluctuation anisotropy observed from PSP first seven orbits
L. -L. Zhao, G. P. Zank, L. Adhikari +1
Solar wind turbulence is anisotropic with respect to the mean magnetic field. Anisotropy leads to ambiguity when interpreting in-situ turbulence observations in the solar wind beca…
Detection of small magnetic flux ropes from the third and fourth Parker Solar Probe encounters
L. -L. Zhao, G. P. Zank, Q. Hu +22
We systematically search for magnetic flux rope structures in the solar wind to within the closest distance to the Sun of 0.13 AU, using data from the third and fourth orbits of th…
