On the possibility of the detection of brown dwarfs in typical debris disk using the spectral energy distribution

During its formation, a planetary or a brown dwarf companion clears the gap along its orbital motion in the protoplanetary disk. The possibility of the detection of the gap that is forming in the disk and the substellar companion in it is investigated based solely on the spectral energy distribution. The results of the simulations for the system at the age of 100 Myr with a low-mass star, a typical debris disk, and a substellar companion are presented. The width of the gap cleared out by the substellar companion is determined by the Hill sphere diameter.
