Dust disk masses as a function of the central object mass (M_*) for Class II BDs. Red stars mark sources in this paper including upper limits (marked with arrows). Black circles correspond to BD and VLM stars in other SFRs such as Ophiuchus (Testi et al. 2016), Upper Scorpius (van der Plas et al. 2016), Chamaeleon I (Pascucci et al. 2016), Taurus (Ricci et al. 2014; Ward-Duong et al. 2018), and Lupus sources that are not part of our survey (Ansdell et al. 2016; Sanchis et al. 2020). Upper limits are included as arrows. All the objects were observed with ALMA and masses were recalculated using T = 20 K for consistency. The grey area represents the predictions for disk fragmentation in Stamatellos & Herczeg (2015), while the blue and green areas are the scaling relations between disk mass and stellar mass for protoplanetary disks derived by Andrews et al. (2013) using three different sets of model calculations (D’Antona & Mazzitelli 1997; Baraffe et al. 1998; Siess et al. 2000). The red vertical line represents the limit between BDs and stars.
