Non-thermal plasma density redistribution in planetary magnetospheres due to ion-cyclotron waves

Joaquín Espinoza-Troni, Felipe A Asenjo, Pablo S Moya

Planetary magnetospheres exhibit diverse environments where Ultra-low frequency (ULF) pulsations induce nonlinear ponderomotive effects. Since suprathermal populations modeled by K…

First Principles Magnetohydrodynamical Theory for the Expanding Box Model

Sebastián Saldivia, Nicolás Villarroel-Sepúlveda, Sebastián Echeverría-Veas +2

The Expanding Box Model (EBM) has been widely employed to simulate multiscale plasma phenomena in the expanding solar wind by transforming the MHD equations to a co-moving, non-ine…

Secondary Electron-Only Reconnection Driven by Large Scale Ion-Coupled Reconnection and Electron Kelvin-Helmholtz Instabilities in Hybrid Simulations of Solar Wind Turbulence

Joaquín Espinoza-Troni, Giuseppe Arrò, Francesco Califano +2

Electron-only reconnection (EREC) is a magnetic reconnection regime occurring within subion-scale current sheets (CSs), exhibiting only electron jets, without any ion outflows. ERE…

Knudsen number as a non-thermal parameter: possible origin of skewness in space plasma distributions

Iván Gallo-Méndez, Adolfo F. Viñas, Pablo S. Moya

Non-Maxwellian distributions and their origins in space plasma have attracted significant attention due to their prevalence and impact on various astrophysical and space-related ph…

Dispersive Properties of MHD Waves in the Expanding Solar Wind for a Parker Spiral Geometry

Sebastián Saldivia, Felipe Asenjo, Pablo S. Moya

In this work, we quantify the effects of solar wind expansion on the dispersive properties of the three normal modes of ideal MHD using the Expanding Box Model, under a background…

Analysis of persistent and antipersistent time series with the Visibility Graph method

Macarena Cádiz, Iván Gallo-Méndez, Pablo S. Moya +1

In this work, we investigate a range of time series, including Gaussian noises (white, pink, and blue), stochastic processes (Ornstein-Uhlenbeck, fractional Brownian motion, and Le…
