Configuration of our assumptions of the Grand Tack scenario in a disc with Zdust = 0.1%. The black lines indicate the orbital distances of 2.0 and 3.5 AU, which correspond to the 2:1 mean motion resonance when the outward migration in the Grand Tack scenario can start. The white lines correspond to the final planetary masses of 200 ME for Jupiter and 70 ME for Saturn. Jupiter’s r0 and t0 are therefore constrained by the crossing between the white 200 ME and the black 2 AU lines, while Saturn is constrained by the white 70 ME line and the black 3.5 AU line. Jupiter forms earlier (smaller t0) and closer to the Sun (smaller r0) than Saturn, showing that the conditions of the Grand Tack scenario can be met.
