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…
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 win…
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…
Observed Fluctuation Enhancement and Departure from WKB Theory in Sub-Alfvénic Solar Wind
David Ruffolo, Panisara Thepthong, Peera Pongkitiwanichakul +12
Using Parker Solar Probe data from orbits 8 through 17, we examine fluctuation amplitudes throughout the critical region where the solar wind flow speed approaches and then exceeds…
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…
The Alfvén Transition Zone observed by the Parker Solar Probe in Young Solar Wind -- Global Properties and Model Comparisons
Rohit Chhiber, Francesco Pecora, Arcadi V Usmanov +6
The transition from subAlfvénic to superAlfvénic flow in the solar atmosphere is examined by means of Parker Solar Probe (PSP) measurements during solar encounters 8 to 14. Around…
Anisotropy of Density Fluctuations in the Solar Wind at 1 au
Jiaming Wang, Rohit Chhiber, Sohom Roy +6
A well-known property of solar wind plasma turbulence is the observed anisotropy of the autocorrelations, or equivalently the spectra, of velocity and magnetic field fluctuations.…
Low-cost, Lightweight Electronic Flow Regulators for Throttling Liquid Rocket Engines
Vint Lee, Sohom Roy
For small-scale liquid rockets, pressure-fed systems are commonly favoured due to their simplicity and low weight. In such systems, accurate regulation of both tank and injector pr…
Relaxation of the turbulent magnetosheath
Francesco Pecora, Yan Yang, Alexandros Chasapis +9
In turbulence, nonlinear terms drive energy transfer from large-scale eddies into small scales through the so-called energy cascade. Turbulence often relaxes toward states that min…
Isotropization and Evolution of Energy-Containing Eddies in Solar Wind Turbulence: Parker Solar Probe, Helios 1, ACE, WIND, and Voyager 1
Manuel Enrique Cuesta, Rohit Chhiber, Sohom Roy +6
We examine the radial evolution of correlation lengths perpendicular (\(λ_C^{\perp}\)) and parallel (\(λ_C^{\parallel}\)) to the magnetic-field direction, computed from solar wind…
Pressure-Strain Interaction as the Energy Dissipation Estimate in Collisionless Plasma
Yan Yang, William H. Matthaeus, Sohom Roy +4
The dissipative mechanism in weakly collisional plasma is a topic that pervades decades of studies without a consensus solution. We compare several energy dissipation estimates bas…
