tardis.plasma.equilibrium.rates.radiative_rates module

class tardis.plasma.equilibrium.rates.radiative_rates.RadiativeRatesSolver(einstein_coefficients)[source]

Bases: object

Calculate bound-bound Einstein transition rates.

einstein_coefficients: DataFrame

solve(mean_intensity: DataFrame, beta_sobolev: DataFrame | None = None) → DataFrame[source]

Calculate line rates from fixed intensities and escape probabilities.

Parameters:

mean_intensitypandas.DataFrame: Mean intensity blueward of each line. Rows follow the Einstein-line index and columns are shells.
beta_sobolevpandas.DataFrame, optional: Candidate Sobolev escape probabilities aligned with mean_intensity. When omitted, all escape probabilities are one.

Returns:

pandas.DataFrame: Upward and downward rates in source–destination index convention.
