This webpage contains the AGB+dust models at metallicities Z=3*10-7, computed as described in Ventura et al. submitted for publication.
Physical and chemical evolution
These files contain the evolution of each initial mass model following the main physical properties (e.g. L, Teff, Mloss) and the surface mass fraction of several chemical elements. We selected one representative point during each thermal pulse. In some cases more than one point is selected at the end of the carbon star phase to better map the evolution when the mass-loss rate is particularly high. Those cases has the same thermal pulse number (1st column)
Gas yelds
This table contains the net gas yields ejected during the AGB evolution for each initial mass model, computed following the equation
Y_i=\int{ [X_i−X^{init}_i ]}\dot{M}dt.The integral is calculated over the entire stellar lifetime, while X^{init}_i is the mass fraction of species i at the beginning of the evolution.
Dust evolution
These files contain the evolution of dust produced in the circumstellar envelope during the AGB phase for each initial mass model. We selected one representative point during each thermal pulse. There is a one-to-one correspondence between these points and the ones selected to describe the physical and chemical evolution.
Dust yelds
This table contains the total amount of dust produced during the AGB phase and the contribution of the different dust compounds.
