Lense-Thirring accretion plane adapted from Middleton et al. (2019). Left and right panels: resulting T_sph and precessing period of the wind for ε_wind = 0.2 and 0.8, respectively. The values expected for a 20 M_⊙ BH with a dimensionless spin of 0.1 are shown in dashed dark blue and could be considered as a rough upper limit for the location of BHs in the plane. The rest of the lines show the values for NSs with different dipole magnetic field strengths, as indicated. The solid and dashed lines show the effect of varying the spin of the NS from 3 × 10⁻⁵ to 3 × 10⁻³, which we have converted to periods assuming canonical values for the moment of inertia and mass of the NS (see the text for details) and represent typical values observed in ULXs.
