Ratio of the core-to-surface rotation rate as a function of gravity for models of KIC 7341231. Black, green, and blue lines correspond to an additional viscosity of 3 × 10⁴, 2 × 10⁴ and 1 × 10⁴ cm² s^-1, respectively. The red dashed and dotted vertical lines correspond to the gravity of KIC 7341231 and KIC 8366239, respectively. The blue region indicates the ratio of the core-to-surface rotation rate that is compatible with the asteroseismic measurements of KIC 7341231.
