Notes. If the radius, Rdon, of a given donor during the ongoing RLOF is found within range RS–RU for Z ≤ 0.5 Z⊙ or below Rdon < RU for Z > 0.5 Z⊙ then we assume stable RLOF, otherwise CE evolution is applied. There are cases where expansion instability was not found for any radius (stable) and where cases where RLOF is unstable over the whole radius range (unstable).
