Nonlinear interactions between gravitational radiation and modified Alfvén modes in astrophysical dusty plasmas

Abstract

We present an investigation of nonlinear interactions between Gravitational Radiation and modified Alfvén modes in astrophysical dusty plasmas. Assuming that stationary charged dust grains form neutralizing background in an electron-ion-dust plasma, we obtain the three wave coupling coefficients, and calculate the growth rates for parametrically coupled gravitational radiation and modified Alfvén-Rao modes. The threshold value of the gravitational wave amplitude associated with convective stabilization is particularly small if the gravitational frequency is close to twice the modified Alfvén wave-frequency. The implication of our results to astrophysical dusty plasmas is discussed.

Transverse wave propagation in relativistic two-fluid plasmas in de Sitter space

“…Servin and Brodin [16] and Kleidis et al [17,18] studied cyclotron damping of the gravitational wave produced from resonant interaction with (collisionless) plasma particles, while Forsberg et al [19] investigated nonlinear interactions between gravitational radiation and modified Alfvén modes in astrophysical dusty plasmas.…”

Dynamic properties of strongly coupled dusty plasmas with particles of finite dimensions

“…It is known that dusty plasmas are widely spread in space objects such as planetary rings, comets tails, interplanetary, and interstellar clouds . On the other hand, dusts can appear in industrial installations in which a plasma is deployed as a working substance, as it is practically impossible to completely avoid its contact with the chamber walls and electrodes .…”

Dynamic structure factor of non-ideal dusty plasmas with finite size macroscopic particles

“…Известно, что пылевая плазма широко распространена в космических объектах, таких как планетарные кольца, хвосты комет, межпланетные и межзвездные облака [1][2][3]. С другой стороны, пыль может появляться в промышленных установках, в которых плазма является рабочим телом, так как полностью избежать ее контакта с твердыми стенками и электродами камеры не представляется возможным [4][5][6].…”
