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…

Estimation of Effective Viscosity to Quantify Collisional Behavior in Collisionless Plasma
Subash Adhikari, Carlos Gonzalez, Yan Yang +4
While dissipation in collisional plasma is defined in terms of viscosity and resistivity, the exact functional form of dissipation i.e., the so-called dissipation function in nearl…

Revisiting compressible and incompressible pressure-strain interaction in kinetic plasma turbulence
Subash Adhikari, Yan Yang, William H. Matthaeus
In this study, we revisit the pressure-strain interaction in kinetic turbulence, and in particular we re-examine the decomposition of pressure-strain interaction into compressive a…
