First Principles Magnetohydrodynamical Theory for the Expanding Box Model: Effects on Expansion-Induced Alfvén Wave Reflection
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…
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…
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…
Unifying Kappa Distribution Models for Non-Equilibrium Space Plasmas: A Superstatistical Approach Based on Moments
Abiam Tamburrini, Sergio Davis, Pablo S. Moya
From the perspective of non-equilibrium statistical mechanics, modeling the velocity distribution of particles in non-equilibrium, steady-state plasmas presents a significant chall…
The effect of plasma expansion on the dispersion properties of MHD waves
Sebastián Saldivia, Felipe A. Asenjo, Pablo S. Moya
In this work, we employ the set of ideal expanding magnetohydrodynamic (MHD) equations within the Expanding Box Model (EBM) framework to theoretically characterize the effects of r…
Electron scale magnetic holes generation driven by Whistler-to-Bernstein mode conversion in fully kinetic plasma turbulence
Joaquín Espinoza-Troni, Giuseppe Arrò, Felipe A Asenjo +1
Magnetic holes (MHs) are coherent structures characterized by a strong and localized magnetic field amplitude dip, commonly observed in the solar wind and planetary magnetosheaths.…
Dark energy as a battery for magnetic field generation in plasmas
Nicolás Villarroel-Sepúlveda, Pablo S. Moya, Felipe A. Asenjo +1
It is shown that in the spacetime dominated by a cosmological constant, in the far region of a Schwarzschild-de Sitter black hole, a seed magnetic field can be generated in an ambi…
Magnetic seed generation by plasma heat flux in accretion disks
Nicolás Villarroel-Sepúlveda, Felipe A. Asenjo, Pablo S. Moya
Context. Magnetic batteries are potential sources that may drive the generation of a seed magnetic field, even if this field is initially zero. These batteries can be the result of…
Expanding CGL: The CGL double-adiabatic approximation in the Expanding Solar Wind
Sebastián Echeverría-Veas, Pablo S. Moya, Marian Lazar +2
Different in situ satellite observations within 0.3 to 1 AU from the Sun reveal deviations in the thermodynamics of solar wind expansion. Specifically, these deviations challenge t…
Ponderomotive forces in magnetized non-thermal space plasmas due to cyclotron waves
Joaquín Espinoza-Troni, Felipe A Asenjo, Pablo S Moya
The ponderomotive force is involved in a variety of space plasmas phenomena which are characterized by the family of Kappa distributions. Therefore, evaluating these nonthermal eff…
