Magnetohydrodynamic waves in solar partially ionized plasmas: two-fluid approach
TL;DR: In this article, the authors derived the dynamics of magnetohydrodynamic (MHD) waves in two-fluid partially ionized plasmas and compared the results with those obtained under a singlefluid description, where ion-electron plasma and neutral particles are considered as separate fluids.
Journal ArticleDOI
Exoplanetary radio emission under different stellar wind conditions

TL;DR: In this paper, it is shown that at close distances the stellar wind is still slow and has not yet reached the velocity it has at larger distances, which correspondingly reduces the intensity of stellar wind-driven planetary radio emission, which is calculated taking into account the stellar age.
Journal ArticleDOI
The influence of stellar wind conditions on the detectability of planetary radio emissions
TL;DR: In this paper, the authors compare the expected stellar and planetary radio signal for stellar systems of different ages, and show that conditions corresponding to the young solar system (i.e., with increased stellar wind density and velocity) appear to be more favorable than for older stellar systems.
Journal ArticleDOI
Damping of Alfvén waves in solar partially ionized plasmas: effect of neutral helium in multi-fluid approach
TL;DR: In this article, the effect of neutral helium in the damping of Alfven waves in solar, partially ionized plasmas was studied. But the results were limited to a three-fluid MHD approximation, where one component is electron-proton-singly ionized helium and the other two components are neutral hydrogen and neutral helium atoms.

Damping of Alfven waves in solar partially ionized plasmas: effect of neutral helium in multi-fluid approach
TL;DR: In this paper, the effect of neutral helium in the damping of Alfven waves in solar partially ionized plasmas was studied. And the authors derived the dispersion relation of linear Alfven wave in isothermal and homogeneous plasma.
