Same as Fig. 9 but with a fixed injection time of 10⁵ yr. Large discs form more giants when the embryos are injected early, which results in fewer super-Earths being formed. In contrast, if no giants are able to form, such as when the host star mass is below 0.5 M_⊙, the super-Earth fraction increases with increasing disc size. We find that the median super-Earth fraction decreases with increasing stellar mass, both with or without viscous heating, although the effect is significantly stronger when viscous heating is active. Further, we find that the median super-Earth fraction increases slightly above 1 M_⊙ in the viscous case as the sampled disc sizes around these high-mass stars are slightly smaller.
