Proton Heating Rates in the Inner Heliosphere: Helios Observations
Alaa Fayad, Anna Tenerani, Chadi Salem
Solar wind protons exhibit a temperature anisotropy that deviates from the double-adiabatic prediction, suggesting an additional energy source. To investigate solar wind heating me…
Spherically Polarized Alfvén Waves and the Gosling Boost
Yuliang Ding, Marco Velli, Zesen Huang +6
Alfvén waves are thought to play critical roles in solar wind acceleration and plasma heating in the solar corona and inner heliosphere. Parker Solar Probe (PSP) has highlighted th…
Nonlinear Tearing Modes in Current-Vortex Sheets
D. Urbanski, F. L. Waelbroeck, A. Tenerani
The linear and nonlinear development of instabilities and Alfvén resonances in a plane current-vortex sheet is presented here for sheared equilibrium profiles $\boldsymbol{B_{y0}}…
Evolution and Impact of Switchbacks Throughout the Heliosphere
Alfred Mallet, Chen Shi, Anna Tenerani +23
Magnetic switchbacks are large-amplitude fluctuations in the interplanetary magnetic field, and appear frequently in the near-Sun solar wind explored recently by Parker Solar Probe…
Three dimensional, spherically polarized magnetic fields
Anna Tenerani, Marco Velli
Turbulence in the solar wind is characterized by Alfvénic fluctuations that exhibit spherical polarization, a geometric condition resulting in the nearly constant magnitude of the…
Resistive instabilities of current sheets in stratified plasmas with a gravitational field
Faisal Sayed, Anna Tenerani, Richard Fitzpatrick
Magnetic reconnection can develop spontaneously via the tearing instability, often invoked to explain disruptive instabilities in fusion devices, solar flares, the generation of pe…
Generation and Expansion-Driven Growth of Switchbacks in the Outer Solar Corona and Solar Wind
Nikos Sioulas, Marco Velli, Chen Shi +6
We analyze \emph{Parker Solar Probe} and \emph{Solar Orbiter} measurements of magnetic-field reversals (``switchbacks'') across the Alfvén surface (), where is t…
Characterization of compressible fluctuations in solar wind streams dominated by balanced and imbalanced turbulence: Parker Solar Probe, Solar Orbiter and Wind observations
C. A. Gonzalez, C. Gonzalez, A. Tenerani
Characterizing compressible fluctuations in the solar wind is essential for understanding their role in solar wind acceleration and heating, yet their origin and evolution across d…
