(a) Mass growth and (b) semimajor axis evolution of planetesimals in a ring located at r = 0.3 AU with type I migration. The same colored plots and lines are used as for Fig. 2. The embryos migrate out of the birth ring when their masses exceed 10−3 M⊕ and stop pebble accretion at the inner edge of the disk. They can further increase their masses via giant impacts.
