Magneto-Gravity Waves in Stellar Interiors

Internal gravity waves change with variations of the background in which they propagate. We present 3 dimensional simulations of internal gravity waves with different background magnetic field configurations, including no background magnetic field, and a uniform vertical magnetic field. We compare the simulations to analytic solutions. Our results show that the frequency of the wave will effect the kinetic and magnetic energy distribution within the simulation. The average energy of the waves is large at certain resonant frequencies. The waves also exhibit critical cylindrical radii, which move towards the outer layers of the star as frequency increases, in accordance with analytic solutions.
