The 'Red Giant Clock' as an indicator for the efficiency of central mixing in horizontal-branch stars
Abstract
New evolutionary evaluations have been compared with observational data for the globular cluster M5 in order to assess the kind of mixing (semiconvection with and without the inclusion of the breathing pulses or overshooting) which takes place in real stars during the central He-burning phase. It is suggested that the evolutionary time scale on the red giant branch should be used to assess the absolute time scale of evolution on the asymptotic giant branch. On this basis, it is found that ordinary semiconvection without breathing pulses leads to the best match to the observed data for M5.

“Nevertheless, appealing again to star counts as a proxy for timescales, the data seem to argue against the reality of these pulses (Renzini & Fusi Pecci 1988; Caputo et al. 1989, but see also Campbell et al. 2013).”

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.
