A new grid of 2,700 accretion models shows that weak Ba, CH, and CEMP-s stars are well reproduced with AGB donors of 2-3 solar masses, while strong Ba stars require accreted masses beyond the grid's 0.5 solar mass limit, which fails to match their observed mass distribution.

Modeling the progenitors of low-mass post-accretion binaries
A new grid of 2,700 accretion models shows that weak Ba, CH, and CEMP-s stars are well reproduced with AGB donors of 2-3 solar masses, while strong Ba stars require accreted masses beyond the grid's 0.5 solar mass limit, which fails to match their observed mass distribution.
