class tardis.plasma.properties.helium_nlte.HeliumNLTE(plasma_parent)

Bases: ProcessingPlasmaProperty

static calculate(level_boltzmann_factor, ionization_data, beta_rad, g, g_electron, w, t_rad, t_electrons, delta, zeta_data, number_density, partition_function)

Updates all of the helium level populations according to the helium NLTE recomb approximation.

static calculate_helium_one(g_electron, beta_rad, ionization_data, level_boltzmann_factor, g, w)

Calculates the He I level population values, in equilibrium with the He II ground state.

static calculate_helium_three(t_rad, w, zeta_data, t_electrons, delta, g_electron, beta_rad, ionization_data, g)

Calculates the He III level population values.

outputs = ('helium_population',)

class tardis.plasma.properties.helium_nlte.HeliumNumericalNLTE(plasma_parent, heating_rate_data_file)

Bases: ProcessingPlasmaProperty

IMPORTANT: This particular property requires a specific numerical NLTE solver and a specific atomic dataset (neither of which are distributed with Tardis) to work.
