Recent results of a mixed shell model heated asymmetrically by transient increases in nuclear burning indicate the transient generation of small ‘hot spots’ inside the Sun somewhere between 0.1 and 0.2 solar radii. These hot bubbles are followed by a nonlinear differential equation system with finite amplitude non-homologous perturbations which is solved in a solar model. Our results show the p...
