The relativistic tidal tensor: general solutions for stationary axisymmetric spacetimes and the Hills mass of naked singularities
Wenkang Xin, Andrew Mummery
The tidal forces experienced on an orbit contain, in principle, information about the underlying spacetime an object is moving through. Astronomical observations often probe the pr…
Black hole supercolliders
Andrew Mummery, Joseph Silk
We show that collisions between particles free falling from infinity and a disk of material plunging off the retrograde innermost stable circular orbit of a near-extremal Kerr blac…
The maximum mass of a black hole which can tidally disrupt a star: measuring black hole spins with tidal disruption events
Andrew Mummery
The tidal acceleration experienced by an object at the event horizon of a black hole decreases as one over the square of the black hole's mass. As such there is a maximum mass at w…
Testing theories of accretion and gravity with super-extremal Kerr discs
Andrew Mummery, Steven Balbus, Adam Ingram
Fitting the thermal continuum emission of accreting black holes observed across X-ray bands represents one of the principle means of constraining the properties (mass and spin) of…
A complete characterisation of the orbital shapes of the non-circular Kerr geodesic solutions with circular orbit constants of motion
Andrew Mummery, Steven Balbus
We present analytical solutions describing a family of both inwardly and outwardly spiralling orbits in the Kerr spacetime. The solutions are exact, and remarkable for their simpli…
Asymptotic Green's function solutions of the general relativistic thin disc equations
Andrew Mummery
The leading order Green's function solutions of the general relativistic thin disc equations are computed, using a pseudo-Newtonian potential and asymptotic Laplace mode matching t…
Inspirals from the innermost stable circular orbit of Kerr black holes: Exact solutions and universal radial flow
Andrew Mummery, Steven Balbus
We present exact solutions of test particle orbits spiralling inward from the innermost stable circular orbit (ISCO) of a Kerr black hole. Our results are valid for any allowed val…
