Part of Speech verb rummage about rummage out rummage up. The final core mass at the tip of the AGB is taken as a proxy for the final white dwarf mass. 26 Opposites of Rummage phrases idioms nouns verbs core fix order v. 4, we show the evolution of the core and the inner edge of the convective. Contrary to previous speculations we show that these events are not recurrent and do not change substantially the final H-content of the cool (DA) white dwarf. This mixing phase is known as third dredge-up (TDU ) and can occur after each thermal pulse. As a matter of fact, we find that these flashes do occur only in some low-mass (M C>O by mass fractions. Based on physically sounding white dwarf models, we find that the range of helium buffer masses for these diffusion-induced novas to occur is significantly smaller than that predicted by the only previous study of this scenario. Then we calculate the consequent white dwarf cooling evolution by means of a consistent treatment of element diffusion and nuclear burning. In order to obtain very thin helium buffers, we simulate the formation of low mass remnants through an AGB final/late thermal pulse (AFTP/LTP scenario). For these stars we explore the possible occurrence of diffusion-induced CNO- flashes, during their early cooling stage. The third dredge-up in low-mass stars according to full TP-AGB calculations. The key point in explaining the kink is the interplay between the third dredge-up (3DU), which determines the surface enrichment in carbon, and the dependence of stellar winds for C stars on the. We propose a scenario for the formation of DA white dwarfs with very thin helium buffers. The third dredge-up and the C-star luminosity functions in the Magellanic Clouds 3 Table 1.
