Fig. 2

Fractional radii (radius/semimajor axis) of six gainers and their accretion disks in the Lubow & Shu diagram. The observed radii of gainers are dots below ϖd. The calculated disk radii are squares above ϖd. The two observed disk radii are triangles. The fractional radii of permanent disks and the position of the gainer’s Roche radius are also indicated.
