# README for Huscher et al. (2025) Mass Loss Rate and Yield Tables
--------------------------------------------------------------------

This directory contains an AGB mass loss rate table and yield tables for C, N, and O presented in:

> Huscher, E. et al. (2025), AGB Mass-loss Rates and Metal Yields from Scaled Mixing-length and Mass-loss Parameters, ApJ


## Notes
----------------

These tables are produced from our grid of MESA models, interpolating to calculate values at the exact stellar ages of 
10^7.18 to 10^10.22 years spaced 10^0.02 apart. They are weighted by a Chabrier IMF and presented as a
function of stellar age and initial metallicity. To match existing input table formats for EAGLE and TECHNICOLOR DAWN simulations, 
each value is normalized by the total stellar mass formed which is calculated by integrating the IMF over 0.1 to 300 solar masses.

AGB_Mdot_table_Huscher25.txt contains instantaneous mass loss rates of AGB stars (M_solar/year)
AGB_Cyield_table_Huscher25.txt contains instantaneous carbon 12 mass fractions of the outflowing gas from AGB stars
AGB_Nyield_table_Huscher25.txt contains instantaneous nitrogen 14 mass fractions of the outflowing gas from AGB stars
AGB_Oyield_table_Huscher25.txt contains instantaneous oxygen 16 mass fractions of the outflowing gas from AGB stars
