Quantifying isochrone-based age uncertainties for rapidly rotating A-type stars
A population-synthesis framework shows rotation and unresolved companions bias isochrone ages by a factor of at least 2 near the ZAMS and by 31% for older A stars, adding ~0.1 solar mass and ~180 Myr random uncertainties.
