Thin-disc theory with a non-zero-torque boundary condition and comparisons with simulations
Thin-disc theory with a non-zero-torque boundary condition and comparisons with simulations
We present an analytical solution for thin disk accretion onto a Kerr black hole that extends the standard Novikov-Thorne alpha-disk in three ways: (i) it incorporates nonzero stresses at the inner edge of the disk, (ii) it extends into the plunging region, and (iii) it uses a corrected vertical gravity …
