Relative radius for the Gainer R₁/a (black dot) and disk (R_d/a (red dot) of V1001 Cen, the gray dots are other DPVs extracted from Table 12 of Mennickent et al. (2016a), and the pink dots represent their disks. Below the circularization radius shown by the dashed black line a disk should form and below the dashed blue line a disk could form. The tidal radius indicates the maximum possible extent of the disk.
