synthesizer.abundances.depletion_models

A module defining depletion model for use in photoionization models.

Module containing various depletion models. Depletion models relate the gas phase depleted abundances to the total abundances, i.e.:

(X/H)_{gas,dep} = D_{x}times (X/H)_{total} (X/H)_{dust} = (1-D_{x})times (X/H)_{total}

Classes

class synthesizer.abundances.depletion_models.CloudyClassic(scale=1.0)

Implementation of the ‘cloudy classic’ depletion pattern.

This is the same as the one that is built into cloudy23.

class synthesizer.abundances.depletion_models.Gutkin2016(scale=1.0)

Depletion pattern created for Synthesizer 2024.

Gutkin+2016 (ui.adsabs.harvard.edu/abs/2016MNRAS.462.1757G/abstract)

Note: in previous version we adjusted N (“N”: 0.89) following Dopita+2006 (ui.adsabs.harvard.edu/abs/2013ApJS..208…10D/abstrac) and Dopita+2013 (ui.adsabs.harvard.edu/abs/2006ApJS..167..177D/abstract)

class synthesizer.abundances.depletion_models.Jenkins2009_Gunasekera2021(fstar=0.5, limit=1.0)

Implemention of the Jenkins (2009) depletion pattern.

This is the model that is built into cloudy23 as described by Gunasekera (2021). This modification adds in additional elements that were not considered by Jenkins (2009).

In this model the depletion (D_x) is written as:

D_x = 10**(B_x +A_x (F_* − z_x ))

where A_x, B_x, and z_X are the fitted parameters for each element while f_* (fstar) is the scaling parameter.
