Fateof the primary star as a function of its mass and initial period for a system with a 9 M_⊙ secondary companion. The triangles indicate an evolution to contact with the cyan triangles corresponding to systems that undergo a reverse case C mass transfer. The open magenta circles and black filled squares label binaries in which the primaryend its life as an ONe WD and ECSN, respectively. The green stars identify systems with a massive He core that evolves as CCSN. The transition between case A and case B mass transfer is delineated by the dotted line and occurs for periods between 2.3 and 2.5 days.
