The origin of planetary system architectures – I. Multiple planet traps in gaseous discs

The structure of planetary systems around their host stars depends on their initial formation conditions. Massive planets will likely be formed as a consequence of rapid migration of planetesimals and low-mass cores into specific trapping sites in protoplanetary discs. We present analytical modelling of inhomogeneities in protoplanetary discs around a variety of young stars – from Herbig Ae/Be to classical T Tauri and down to M stars – and show …
