Comparison of disc properties for a disc around an M dwarf and a solar-type star in our model. Left: Aspect ratio of a disc around a 0.1 M_⊙ star (black lines) and a disc around a 1.0 M_⊙ star (orange lines) for low (solid lines) and high (dashed lines) disc viscosities. Right: Viscous accretion timescale of the discs as a function of radial distance, stellar mass, and disc viscosity. Solid circles indicate the location of the water-ice (blue) and CH₄-ice (red) lines in each disc.
