We find that the thin, cold disc transitions to a thick, hot accretion flow at a radius dependent on the mass accretion rate due to proton-electron Coulomb decoupling. At high accretion rates, the disc truncates close to the innermost stable circular orbit $r\\approx2r_g$, demonstrating that even in the can","authors_text":"A. Hankla, J. Dexter, N.
