tardis.io.model.parse_density_configuration module

tardis.io.model.parse_density_configuration.calculate_density_after_time(densities: Quantity, time_0: Quantity, time_explosion: Quantity) → Quantity

scale the density from an initial time of the model to the time of the explosion by ^-3

Parameters:

densitiesastropy.units.Quantity

densities

time_0astropy.units.Quantity

time of the model

time_explosionastropy.units.Quantity

time to be scaled to

Returns:

scaled_densityastropy.units.Quantity

in g / cm^3

tardis.io.model.parse_density_configuration.calculate_exponential_density(velocities: Quantity, velocity_0: Quantity, rho_0: Quantity) → Quantity

This function computes the exponential density profile. \(\rho = \rho_0 \times \exp \left( -\frac{v}{v_0} \right)\)

Parameters:

velocitiesastropy.Quantity

Array like velocity profile

velocity_0astropy.Quantity

reference velocity

rho_0astropy.Quantity

reference density

Returns:

densitiesastropy.Quantity

tardis.io.model.parse_density_configuration.calculate_power_law_density(velocities: Quantity, velocity_0: Quantity, rho_0: Quantity, exponent: float) → Quantity

This function computes a descret exponential density profile. \(\rho = \rho_0 \times \left( \frac{v}{v_0} \right)^n\)

Parameters:

velocitiesastropy.Quantity

Array like velocity profile

velocity_0astropy.Quantity

reference velocity

rho_0astropy.Quantity

reference density

exponentfloat

exponent used in the powerlaw

Returns:

densitiesastropy.Quantity

tardis.io.model.parse_density_configuration.parse_density_from_csvy(csvy_model_config, csvy_model_data, time_explosion)

Parse the density data from a CSVY model.

Parameters:

csvy_model_configobject

The configuration data of the CSVY model.

csvy_model_dataobject

The data of the CSVY model.

time_explosionfloat

The time of the explosion.

Returns:

densityobject

The parsed density data.

Raises:

None.

Notes

This function parses the density data from a CSVY model. If the CSVY model configuration contains a ‘density’ attribute, it uses the ‘parse_csvy_density’ function to parse the density data. Otherwise, it calculates the density data using the ‘calculate_density_after_time’ function. The parsed density data is returned.

tardis.io.model.parse_density_configuration.parse_density_section_config(density_configuration: ConfigurationNameSpace, v_middle: Quantity, time_explosion: Quantity) → Tuple[Quantity, Quantity]

Parse the density section of the configuration file and produce a density at time_explosion.

Parameters:

density_configurationtardis.io.config_reader.Configuration

v_middleastropy.Quantity

middle of the velocity bins

time_explosionastropy.Quantity

time of the explosion

Returns:

density_0astropy.Quantity

density at time_0

time_0astropy.Quantity

time of the density profile

tardis.io.model.parse_density_configuration.parse_density_section_csvy(csvy_model_config: Configuration, time_explosion: Quantity) → Quantity

Parse the density section of the csvy file and produce a density at time_explosion.

Parameters:

configtardis.io.config_reader.Configuration
