Comparison of observed Hα profile (blue) with composite PoWR models. (Left) Hα reproduced by a model with strong wind (log Ṁ = −6.2) assuming it is mostly coming from the stripped star. (Right) Hα feature reproduced by a composite (red dashed) of strong disk emission from the Be star (green dashed) and weak absorption component (log Ṁ = −7.2) from the stripped star (brown dotted).
