Stars from the Inside, Ch The Sun as a test: calibration, sound, neutrinos and a magnetised atmosphere
Problem
The calibrated standard solar model is built from observed inputs, two calibrated parameters adjusted to reproduce the present Sun, and a set of predictions that are checked afterwards against independent data. For each quantity below, state whether it is (i) an observed input, (ii) a calibrated parameter, or (iii) a prediction of the model.
((a)) The solar mass M⊙.
((b)) The meteoritic age of the Sun, 4.57Gyr.
((c)) The initial helium mass fraction Y0.
((d)) The mixing-length parameter αMLT.
((e)) The depth of the base of the convection zone.
((f)) The total boron-8 neutrino flux.
