It provides the most precise tests of the theory of stellar structure and evolution, for example it motivated a revision of the standard model of particle physics to solve the solar neutrino problem. how to say dave in frenchHelioseismology, a term coined by Douglas Gough, is the study of the structure and dynamics of the Sun through its oscillations. These are principally caused by sound waves that are continuously driven and damped by convection near the Sun's surface. It is similar to geoseismology, or asteroseismology (also … Meer weergeven Solar oscillation modes are interpreted as resonant vibrations of a roughly spherically symmetric self-gravitating fluid in hydrostatic equilibrium.
