Amount of angular momentum (AM) gained during the stable reverse-mass-transfer phase (blue; dots) and the amount of AM lost between the end of the mass transfer and core carbon depletion (red, cross) for the models in Figure A.2. The shortest-period systems gain the most angular momentum, but also lose more angular momentum due to their large radial extension compared to long-period binaries. The fractional loss is approximately 80% of the AM gained at each initial period.
