Properties of the He layer burning on the surface of WD in the plane of WD mass and accretion rate, in which the super-Eddington wind is triggered when L_prime = L_Edd. The red solid line shows the Eddington accretion rate Ṁ_Edd, whereas the green solid line presents the minimum accretion rate Ṁ_st for stable He layer burning. For comparison, we also present the boundaries of (black dashed line) by setting L_nuc = L_Edd and Ṁ_RG (blue dotted line).
