Implications of Boron Surface Abundances in Massive Stars
Documenten bij dit artikel
Version PDF originaleAbstract
The evolution of massive stars can be influenced by rotationally induced internal mixing, for which surface boron abundances can serve as a key indicator. We compare rotating single star models to observational data from massive stars with boron observation. Through a Bayesian analysis, we find that about two-thirds of the stars in our sample are well represented by the models, confirming the existence of rotational mixing in radiative stellar envelopes. They were well represented by the models with 50% weaker rotational mixing than the widely adopted one. However, one-third of the stars, which are mostly boron-depleted slow rotators, do not fit the models, suggesting that these stars may have experienced a different boron depletion mechanism or formation channel, such as a binary merger.
