Log M_acc(M_⊙/yr) versus log M_*(M_⊙) for the four accretors in our sample (cyan dots), together with the previously identified members of the Lupus (black dots). The blue crossed squares represent the sub-stellar accreting companions detected at wide orbits by Zhou et al. (2014) around GQ Tau, GSC 06214 00210, and DH Tau as labeled. 2MASS J15551027-3455045, GQ Lup c and 2MASS J16085953-3856275 are also labeled. 2MASS J15523574-3344288 is labeled as a red dot. The continuous red line indicates the double power-law prediction of Vorobyov & Basu (2009), while the magenta dashed line shows the prediction of the disk fragmentation model by Stamatellos & Herczeg (2015).
