On the Statistics of Elsasser Increments in Solar Wind and Magnetohydrodynamic Turbulence
Juan C. Palacios, Sofiane Bourouaine, Jean C. Perez
We investigate the dependency with scale of the empirical probability distribution functions (PDF) of Elsasser increments using large sets of WIND data (collected between 1995 and…
Features of magnetic field switchbacks in relation to the local-field geometry of large-amplitude Alfvénic oscillations: \emph{Wind} and \emph{PSP} observations
S. Bourouaine, J. C. Perez, N. E. Raouafi +3
In this letter we report observations of magnetic switchback (SB) features near 1 au using data from the \emph{Wind} spacecraft. These features appear to be strikingly similar to t…
Applicability of Taylor's Hypothesis during Parker Solar Probe perihelia
Jean C. Perez, Sofiane Bourouaine, Christopher H. K. Chen +1
We investigate the validity of Taylor's Hypothesis (TH) in the analysis of Alfvénic fluctuations of velocity and magnetic fields in solar wind streams measured by Parker Solar Prob…
How Alfvén waves energize the solar wind: heat vs work
Jean C. Perez, Benjamin D. G. Chandran, Kristopher G. Klein +1
A growing body of evidence suggests that the solar wind is powered to a large extent by an Alfvén-wave (AW) energy flux. AWs energize the solar wind via two mechanisms: heating and…
The Eulerian space-time correlation of strong Magnetohydrodynamic Turbulence
Jean C. Perez, Sofiane Bourouaine
The Eulerian space-time correlation of strong Magnetohydrodynamic (MHD) turbulence in strongly magnetized plasmas is investigated by means of direct numerical simulations of Reduce…
Interpreting solar wind turbulent spectra beyond Taylor's Hypothesis
Sofiane Bourouaine, Jean C Perez
In this paper we apply a methodology, recently proposed by Bourouaine and Perez (2019) (BP19), to interpret solar-wind turbulent power spectra beyond Taylor approximation (TA). The…
