Abstract EN
The nonlinear normal mode dynamics is likely to be modified due to nonlinear, dissipative, and dispersive mechanisms in solar plasma system.
Here we apply a plasma-based gravitoelectrostatic sheath (GES) model for the steady-state description of the nonlinear normal mode behavior of the gravitoacoustic wave in field-free quasineutral solar plasma.
The plasma-boundary wall interaction process is considered in global hydrodynamical homogeneous equilibrium under spherical geometry approximation idealistically.
Accordingly, a unique form of KdV-Burger (KdV-B) equation in the lowest-order perturbed GES potential is methodologically obtained by standard perturbation technique.
This equation is both analytically and numerically found to yield the GES nonlinear eigenmodes in the form of shock-like structures.
The shock amplitudes are determined (~0.01 V) at the solar surface and beyond at 1 AU as well.
Analytical and numerical calculations are in good agreement.
The obtained results are compared with those of others.
Possible results, discussions, and main conclusions relevant to astrophysical context are presented.
