A robust empirical relationship between speed and turbulence energy in the near-Earth solar wind
Rohit Chhiber, Yanwen Wang, Manuel E. Cuesta +2
The connection between turbulence and solar-wind acceleration, long known in space physics, is further developed in this Letter by establishing a robust empirical law that relates…
Interplanetary magnetic correlation and low-frequency spectrum over many solar rotations
Jiaming Wang, Francesco Pecora, Rohit Chhiber +2
Fluctuations and structure across a wide range of spatial and temporal scales are frequently studied in the solar wind. The properties of the low-frequency fluctuations are of rele…
von Karman - Howarth Similarity of Spatial Correlations and the Distribution of Correlation Lengths in Solar Photospheric Turbulence
Rohit Chhiber, Raphael Attie, William H. Matthaeus +2
Fluctuations in the Sun's photospheric magnetic field are the primary source of the turbulence that can heat and accelerate the solar atmosphere, and thus play an important role in…
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…
Noise in the Heliosphere: A Target for PUNCH Science
Jiaming Wang, William H. Matthaeus, Rohit Chhiber +4
We present a broad review of 1/f noise observations in the heliosphere, and discuss and complement the theoretical background of generic 1/f models as relevant to NASA's PUNCH miss…
