  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.
