| Abstract: |
Knowledge of the yields produced by intermediate-mass stars during
the thermal-pulse phase is important for a number of topics which are
open issues in astrophysics, e.g. dust production at high redshifts,
the self-enrichment mechanism in globular clusters, accounting for
the luminosity function of carbon and lithium-rich stars
in the Magellanic Clouds, and the integrated spectra of distant
galaxies. We discuss and compare the two mechanisms that can potentially
alter the surface chemistry of these stars, i.e. Hot Bottom Burning
and the Third Dredge-Up, outlining the range of masses where each of them
is dominant, and discussing the relative uncertainties. We also discuss
the yields from Super-AGB stars, which evolve through the thermal pulse
phase with a degenerate core of neon and oxygen. |
