Solar-Cycle Modulation and Photospheric Magnetic Control of Turbulence in the Young Solar Wind
Yanwen Wang, Rohit Chhiber, Arcadi V. Usmanov +2
The solar wind is an outflow of solar plasma that expands from the corona to fill the heliosphere. Its turbulence provides a pathway for non-adiabatic heating and acceleration, and…
Dynamical Age of Alfvénic Turbulence in the Solar Wind
Rohit Chhiber, Yanwen Wang, Arcadi V. Usmanov +1
An evolving turbulent flow such as the solar wind can be meaningfully characterized by its "turbulence age" -- an estimate of the number of nonlinear times that have elapsed during…
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 w…
The effect of turbulence on the angular momentum of the solar wind
Rohit Chhiber, Arcadi Usmanov, William H. Matthaeus +1
The transfer of a star's angular momentum to its atmosphere is a topic of considerable and wide-ranging interest in astrophysics. This letter considers the effect of kinetic and ma…
