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…
Wave-particle equilibria with heavy ions in weakly collisional space plasmas
Nicolás Villarroel-Sepúlveda, Daniel Verscharen, Pablo S. Moya +2
Space plasmas are weakly collisional since characteristic time scales related to Coulomb collisions are much larger than those of Larmor gyration or wave--particle interactions. Th…
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…
The role of the thermal properties of electrons on the dispersion properties of Alfvén waves in space plasmas
Nicolás Villarroel-Sepúlveda, Pablo S. Moya, Rodrigo A. López +1
Context. The transition from left-hand to right-hand polarized Alfvén waves depends on the wavenumber, the ratio of kinetic to magnetic pressure , temperature anisotropy, and io…
