![]() ![]() Obviously, if this is correct, such a star should not experience the third dredge - up. each model, allowing us to calculate the third dredge-up parameter for each case. The species most affected are also indicated. such a star, based on the observed initial - final mass relation. The few other denizens looked up from their hammocks, offering nothing but. as the second dredge up, and in some stars there may even be a third dredge up. When his blindfold was removed, a sickly man showed him a mass grave filled. These constraints derive from newly discovered (bright) white dwarfs in the nearby Hyades and Praesepe star clusters, including a total of 18 high signal-to-noise ratio measurements with progenitor masses of M, just in the proximity of the expected peak in the TP-AGB lifetimes (for MC metallicities), and for ages of ∼1.6 Gyr. A schematic diagram showing the mass dependence of the different dredge-up, mixing, and nucleosynthesis events. The core of a red-giant-branch star of up to a few solar masses stops. We establish new constraints on the intermediate-mass range of the initial-final mass relation, and apply the results to study the evolution of stars on the thermally pulsing asymptotic giant branch (TP-AGB). ![]()
