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…
Inertial-Range Energy Transfer Free from Isotropic Assumption in Turbulent Space Plasma
Zhuoran Gao, Yan Yang, Francesco Pecora +5
The idea of an energy cascade in the inertial range is often invoked in turbulent space plasmas to estimate the energy dissipation rate. Laws governing the behavior of third-order…
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…
Polarimeter to Unify the Corona and Heliosphere (PUNCH)
Craig E. DeForest, Sarah E. Gibson, Ronnie Killough +74
The Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission is a NASA Small Explorer to determine the cross-scale processes that unify the solar corona and heliosphere. PUN…
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…
Angular dependence of third-order law in anisotropic MHD turbulence
Bin Jiang, Zhuoran Gao, Yan Yang +6
In solar wind turbulence, the energy transfer/dissipation rate is typically estimated using MHD third-order structure functions calculated using spacecraft observations. However, t…
