stars

Option	Description
metallicity	Description: This sets the metallicity of the stars, i.e. the amount (by mass) of matter which is not hydrogen or helium. If you are using the BSE algorithm, this must be 1e-4 <= metallicity <= 0.03. See also nucsyn_metallicity and effective_metallicity. Parameter input type: Float Default value: 0.02
effective_metallicity	Description: This sets effective metallicity of stars as used in routines like the Schneider wind loss. If not set, or set to DEFAULT_TO_METALLICITY (==-1, the default), this is just the same as metallicity. The main difference between effective_metallicity and metallicity is the range of validity: 0 <= effective_metallicity <= 1, while metallicity’s range of validity is limited by the stellar evolution algorithm (so, for BSE, is 1e-4 <= metallicity <= 0.03). Parameter input type: Float Default value: -1 Macros: [‘DEFAULT_TO_METALLICITY = -1’, ‘Random variation : double between 0 and 0.03 ‘]

RLOF_interpolation_method	Description: When a star overflows its Roche lobe, it always has R>RL because of the limited time resolution of the simulation.

You can choose algorithm 0, the Hurley et al 2002 method which reverses time (i.e. uses a Newton-like scheme), or 1 to use the binary_c method which rejects a timestep (and hence does no logging on that timestep) and repeats with half the timestep until R~RL. The latter is now the default, because this means there are no negative timesteps which break various other algorithms (e.g. nucleosynthesis).
