    • n dredge An apparatus for bringing up marine animals, plants, and other objects from the bottom of the sea for scientific investigation. It consists principally of a frame of iron and a net which is attached to the frame. As generally constructed, the frame is transversely oblong, generally about three times as long as wide, with straight ends and slightly inclined sides, having the outer edges sharp to serve as scrapers. The net is usually composed of heavy twine, but sometimes of iron chainwork, and is attached to the frame by holes near the inner edges. Fastened to the frame are iron handles, to which a rope or iron chain is attached.

In science:

TPAGB models (Marigo & Girardi 2006), so as to relax the assumption of constant dredge-up parameters characterizing several works in the past literature (e.g.
Population synthesis models including AGB stars and their ingredients
TP-AGB models, obtained with different assumptions concerning the third dredge-up, mass-loss rates, molecular opacities, etc.
Population synthesis models including AGB stars and their ingredients
Different is the case of τM , which is practically independent of mass loss (for AGB stars that later become C-stars), while it is crucially affected by the third dredge-up, since its duration is limited by the transition to the C-star domain.
Population synthesis models including AGB stars and their ingredients
Another mechanism has been outlined by , who has shown that a combination of convective overshooting and partial mixing (implemented via a diffusion equation) can produce both extensive dredge-up and a 13C pocket.
Nucleosynthesis in Intermediate-Mass Asymptotic Giant Branch Stars
The next consequence of HBB is that the 12C which has been added to the envelope after each dredge-up event is now processed by the CN cycle into 13C and 14N.
Nucleosynthesis in Intermediate-Mass Asymptotic Giant Branch Stars
Both HBB and dredge-up require a reasonably large envelope mass.
Nucleosynthesis in Intermediate-Mass Asymptotic Giant Branch Stars
But which ceases first? Dredge-up or HBB? It was recently shown by that HBB is the first to end, while dredge-up continues.
Nucleosynthesis in Intermediate-Mass Asymptotic Giant Branch Stars
But the one uncertainty which I do wish to elaborate on (slightly) is that of dredge-up.
Nucleosynthesis in Intermediate-Mass Asymptotic Giant Branch Stars
There has been, and continues to be, a large disparity in the extent (or even occurrence) of dredge-up found by various authors.
Nucleosynthesis in Intermediate-Mass Asymptotic Giant Branch Stars
Their models show deep dredge-up, which saturates at a level independent of further changes of the numerical parameters () which is consistent with calculations by .
Nucleosynthesis in Intermediate-Mass Asymptotic Giant Branch Stars
We find dramatic changes for the abundances within the intershell region as well as for the mechanism of the 3rd dredge-up.
Overshoot in Giant Stars
About 350 yr after the TP the envelope convection reaches into the intershell layer and material previously partially processed by helium burning is dredged-up to the surface.
Overshoot in Giant Stars
Figure 2: The dredge-up efficiency λ = ∆MDUP/∆M H as a function of the core mass for models with overshoot (full symbols, this work) and without overshoot (open symbols) by Straniero et al. (1997).
Overshoot in Giant Stars
Also note, that dredge-up below the He-flash convection lead s to a phase where the temperature at the bottom of the convective boundary exceeds T ≃ 2.7 · 108 K, which lasts for about 30 yr while models without overshoot have a much shorter high-T phase of only a few years.
Overshoot in Giant Stars
Maybe one of the most compelling aspects of models with overshoot is the ease with which they produce low-mass carbon stars due to efficient dredge-up.
