Wind.ionization

The approach used by Python to calculate the ionization of the wind during ionization cycles. A number of these modes are historical or included for diagnostic purposes.

Type

Enumerator

Values
on.the.spot

Use a simple on the spot approximation to calculated the ionization.

LTE_te

Calculate ionization based on the Saha equation using the electron temperature. (This is intended as a diagnostic mode.)

LTE_tr

Calculate ionization based on the Saha equation using the radiation temperature. (This is intended as a diagnstic mode)

ML93

Use the modified on the spot approimation described by Mazzli & Lucy 1993

fixed

Read the ion aboundances in from a file. All cells will have the same abundances. (This is intended as a diagnostic mode, mainly to investigate the details of raditive transrfer. It should be used with caution. In particular, if the elements for which abundances are provided differ from the elements to be used as described in the elements/ions portion of the atomic data, then one should not expect the calculated electron density to be that that comes simply from the fixd concetnrations file.)

matrix_bb

Estimate photoionization rates by approximating the spectrum in each cell based on the radiation temperature and an effective weight. Invert the rate matrix equations to calculate the ionization

matrix_pow

Estimate photionization rates by approximating the spectrum in a cell by a piecewise approximation, usually a power law. Invert the rate matrix equation to calculate the ionization. (This is the preferred ionization mode for most calculations)

matrix_est

Estimate photionization rates by calculating rates directly from the photons that pass through a cell. There is no attempt to model the spectrum. Invert the rate matrix equation to calculate the ionization.
