Rubidium and zirconium abundances in massive Galactic asymptotic giant branch stars revisited

Context. Luminous Galactic OH/IR stars have been identified as massive (>4–5 M⊙) asymptotic giant branch (AGB) stars experiencing hot bottom burning and Li production. Their Rb abundances and [Rb/Zr] ratios, as derived from classical hydrostatic model atmospheres, are significantly higher than pr...
