Document Summary
Part 12: probing the interior of the sun (helioseismology), the solar neutrinos, the solar wind. The standard solar model: known properties of the sun. 73% h, 25% he, 2% all other elements: assumptions. Energy is transported w/n the sun via radiation & convection: goal. Calculate the temp and density profiles of the sun & compare them w/ observations: helioseismology. The study of how the pressure waves propagate w/n the sun. Motion of material & energy transport inside the sun results in waves on the surface of the sun. Many different wavelengths on surface of the sun. By analyzing vibrations, one can profile the variations in density & temp w/n the sun. Analogy: duck pond: by analyzing the wavelets at the shore, we could say where the ducks are & how. The studies confirmed the standard solar model w/ high degree of accuracy fast they are moving.
