pynucastro.mesa_utils module

A collection of methods for accessing data from a MESA models as read by py_mesa_reader, and putting them into a form that pynucastro can use.

pynucastro.mesa_utils.get_all_data(model)

Return a dictionary keyed by MESA zone index containing the thermodynamic information (rho, T, composition) for all the zones in the model.

Parameters:

model (mesa_reader.MesaData) – The MESA model as read by mesa_reader.MesaData

Return type:

dict[int, tuple(float, float, Composition)]

pynucastro.mesa_utils.get_nuclei(model)

Return a list of nuclei contained in the MESA model.

Parameters:

model (mesa_reader.MesaData) – The MESA model as read by mesa_reader.MesaData

Return type:

list(Nucleus)

pynucastro.mesa_utils.get_zone_data(model, i, *, nuclei=None)

Return a tuple of (rho, T, composition) for a single zone from the MESA model. These are the thermodynamic conditions needed to evaluate a pynucastro network’s rates.

Parameters:

• model (mesa_reader.MesaData) – The MESA model as read by mesa_reader.MesaData

• i (int) – The MESA zone index

• nuclei (list(Nucleus)) – The list of nuclei in the MESA model. This will be read from the model if not provided, but if you are looping over multiple zones in succession, passing a cached list in can speed up the reading.

Return type:

tuple(float, float, Composition)
