On effective radiational gravity acceleration at the interface of dense plasmas and vacuum

Abstract

Radiative, gravitational surface waves are investigated at the interface of high density and low temperature, magnetized incompressible electron-ion plasmas in the presence of dense radiation electromagnetic radiation pressure (DEMRP). The inhomogeneous embedded is reported at plasma-vacuum interface. The DEMRP is found to stabilize the surface waves, however for a specific case, it tends to enhance the growth rate of surface waves via the frictional instability. The group velocity of gravitational radiation is shown to be the function of wavelength. The obtained analytical results are presented both numerically and graphically as function of DEMRP. to show that the incorporation of DEMRP may introduce quite different dispersive properties of charged surface wave phenomena. It is shown numerically that the frequency of the obtained radiative gravitational waves in the presence of DEMRP is found to lie in the range of high frequency radio waves, while in case of rare laboratory plasma, the frequency of these waves is found to lie within the very low frequency radio waves of the electromagnetic radiation spectrum. This work may enhance the gravitational aspects of electromagnetic radiations in dense astrophysical systems such as neutron star and white dwarfs.
