Hα luminosity L(Hα) vs. decay power absorbed by the H-rich stripped material from the companion. The two black lines correspond to the cases where L(Hα) = ė_abs(H-rich) and L(Hα) = 0.1ė_abs(H-rich). For most models, Hα radiates about 10% (the distribution covers from 5 to 30% due to several outliers, all for a low stripped material mass) of the decay power absorbed by the stripped material (this material is ⁵⁶Ni deficient and thus the power stems from non-local γ-ray energy deposition).
