Low-frequency Intermittency and Structures in the Solar Wind at 1 au

Jiaming Wang, Francesco Pecora, Yan Yang +1

Intermittency in the solar wind is commonly studied within the inertial and dissipative ranges, where scale-dependent magnetic field distributions become increasingly non-Gaussian…

Averaging Effects on the Solar Wind Alfven Mach Number: Implications for Switchbacks and Alfven Transition

Joshua Goodwill, Subash Adhikari, Francesco Pecora +10

Averaging techniques in solar wind measurements have been a longstanding subject of debate. Using Parker Solar Probe (PSP) observations from encounters 1 to 19, we investigate how…

Noise in Synthetic and Solar Wind Data: Superposition Principles

Jiaming Wang, Francesco Pecora, Rohit Chhiber +3

The interplanetary magnetic field exhibits a distinctive spectral density from frequencies of around $\unit[10^{-6}]{Hz}$ to around $\unit[10^{-4}]{Hz}$, ranging from harmoni…

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…

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.…
