These objects are likely responsible for radial substructures in the targets of the DSHARP survey. The formation of these objects requires the streaming instability, which occurs when radial drift enhances the local solid-to-gas ratio at pressure bumps. The two main classes of these objects are differentiated by whether they form inside or outside of the snow line. (15[1])Outside the snow line, (15[1])the Toomre (“TOOM-ray”) Q parameter (-5[1])may exceed 1 near icy (*) cores, causing gas to fragment into rings that collapse to form these objects due to gravitational instability. In the core accretion model, these are the largest objects to form in disks surrounding T Tauri stars, where they form from inelastic (10[1])collisions (10[1])between kilometer-sized [these objects]-esimals. (10[2])For 10 points, (10[1])name these spheroidal objects that can be terrestrial (10[2])or Jovian. (10[1])■END■ (10[2])
