Stellar yields from low and intermediate-mass stars. If you use these data please provide a reference to the following paper: Karakas & Lattanzio (2007, PASA) The Stellar Yields ------------------ Individual files for each mass and metallicity are found in: Yields for all of the Z=0.02 models are in the directory z02/ Yields for all of the Z=0.008 models are in the directory z008/ Yields for all of the Z=0.004 models are in the directory z004/ Yields for all of the Z=0.0001 models are in the directory z0001/ Each directory contains two sub-directories: 1) Yields/ 2) PNe/ The header of the files in each sub-directory list the initial and final mass. There are also two sets of files for models with (e.g. m2.5z02_llast.dat) and without (e.g. m2.5z02_llast0.0.dat) synthetic thermal pulses. 1) Yields/ Stellar yields integrated over the entire lifetime. Each file contains as a header the initial and final 2) PNe/ Stellar yields and average abundances in the wind in the mass lost over the last two thermal pulses. Format of the Data ------------------ Yields for the entire stellar lifetime 1) species i 2) atomic mass of the species i 3) nett yield (Msun) 4) mass of species i lost in the wind (Msun) 5) mass of species i initially present in the wind (Msun) 6) the average abundance of species i in the wind (mass fraction) 7) initial mass fraction of species i (mass fraction) 8) production factor, f = log10( average abundance of i / initial abundance ) Yields for planetary nebulae contain: - total mass ejected over the final two TPs (Msun) 1) species i 2) atomic mass of the species i 3) nett yield (Msun) 4) mass of species i lost from the final two TPs (Msun) 5) initial mass fraction of species i (mass fraction) 6) the average abundance of species i in the wind lost over the last two TPs (mass fraction) 7) the abundance of species i by number, divided by the number of hydrogen atoms in the matter expelled over the final two TPs Synthetic Thermal pulses ------------------------ For models that had at least one TP computed using the synthetic algorithm, we provide two sets of yields: 1) m2.5z02_llast0.0.dat: We assumed a zero contribution from these final TPs; this was done by setting lambda equal to zero. Yields are presented in the same way as above, one file for the total yield, another for planetary nebulae. 2) m2.5z02_llast.dat: Here we assumed that the TDU efficiency during these final TPs is a constant value, given by the lambda of the last thermal pulse. See Section 4 of Karakas & Lattanzio (2007) for more details. Yields are presented in the same way as above, one file for the total yield, another for planetary nebulae.
