Stellar evolution is performed by the rapid single-star evolution (SSE)
This is a package of analytical formulae fitted to the detailed models of
Pols et al. (1998)
that covers all phases of evolution from the
zero-age main-sequence up to and including remnant phases.
It is valid for masses in the range 0.1-100 Msun and metallicity
can be varied.
The SSE package contains a prescription for mass loss by stellar winds.
It also follows the evolution of rotational angular momentum for the star.
Full details can be found in the SSE paper:
Hurley, Pols & Tout (2000).
