We investigate the effect of black hole spin on warped or misaligned accretion discs – in particular (i) whether or not the inner disc edge aligns with the black hole spin and (ii) whether the disc can maintain a smooth transition between an aligned inner disc and a misaligned outer disc, known as t...
