SolarAbund Class

• Simple Examples

Overview

This class provides access to element abundance ratios measured in (or nearby) the Sun.

To access the abundances, make a new class instance:

>>> from linetools.abund import solar as labsol
>>> sol = labsol.SolarAbund()
Loading abundances from Asplund2009
Abundances are relative by number on a logarithmic scale with H=12

Then select the element you want by either its name or atomic number:

>>> print(sol['C'])
8.43
>>> print(sol[6])
8.43

Currently the abundances from Asplund et al. 2009 are available, and in future more references will be included.

Multiple elements can also be selected:

>>> print(sol['C', 'O']) 
[8.43 8.69]

Element ratios can be accessed using the get_ratio method:

>>> print(sol.get_ratio('C/Fe')) 
0.98
