... i-iii. Answer question (a) iii, iv and v for the dynamical timescale. iv. In stellar evolution models one often assumes that stars evolve quasi-statically, i.e. that the star remains in hydrostatic equilibrium throughout. Why can we make this assumption? v. Rapid changes that are sometimes observed ...
