Precursor spin-up timescale is plotted as a function of the radius of the ice sublimating area (patch), r_ps, from Equation (15). Solid and dashed curves (black) show k_T = 0.05 and 0.007 (D. Jewitt 1997, 2021), respectively. A horizontal band (yellow) indicates the range of spin-up timescales constrained both by orbital period and empirical observations. The two curves within the band highlight the parameter space where rotational destruction can occur.
