Further inside into p-mode excitation and damping from recent BiSON data
Abstract
The resonant p-mode oscillations of the Sun are believed to be excited stochastically in its outer layers. Here, we seek to gain additional insight into the p-mode excitation and damping problem by following the power evolution, with time, of individual low-degree (low-ell) multiplets. Sine-wave fits have been performed -- at the appropriate frequencies -- on short stretches of high-quality Doppler velocity data, collected in integrated sunlight by the Birmingham Solar-Oscillations Network (BiSON). The results of these analyses will be presented and discussed.
