Thermal pulses; p-capture, alpha-capture, s-process nucleosynthesis; and convective mixing in a star of intermediate mass
Abstract
Schwarzschild and Haerm (1967), and Sanders (1967) have suggested that the synthesis of elements by slow neutron capture on iron and on elements heavier than iron may take place in stars undergoing thermal pulses. The drawbacks of the various specific mechanisms that have been proposed by various investigators are pointed out, noting at the same time that all the mechanisms have one common feature - many repeated neutron bursts separated by long periods of quiescence - which seems to be a crucial element in obtaining a cosmic distribution of s-process elements. A scheme capable of producing repeated neutron bursts and bringing neutron-capture products to the surface is proposed for stars experiencing thermal pulses.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
