Abstract

We review several outcomes of disk gravitational fragmentation in the early evolution of solar-mass protostars. In particular, we focus on the ejection of fragments into the intracluster medium, formation of wide-separation brown-dwarf companions to solar-type stars and annealing of amorphous silicates in the depths of massive and hot fragments.
