Final planet mass as a function of injection location for different stellar masses and disc sizes, for a fixed injection time of t = 10⁵ yr. For low-mass stars, neither disc model produces any super-Earths or giant planets. In the viscous model, the region where giant planets form moves close to the star for larger discs and stellar masses, resulting in fewer super-Earths forming. In the irradiated case, the giant-forming region remains far out in the disc and only moves slightly closer to the star for higher stellar masses.
