Pseudo-Newtonian simulation of a thin accretion disk around a Reissner-Nordström naked singularity
Miljenko Čemeljić, Włodek Kluźniak, Ruchi Mishra +1
We present the first numerical simulations of a thin accretion disk around a Reissner-Nordström (RN) naked singularity (a charged point mass). The gravity of the RN naked singulari…

Equilibrium tori orbiting Reissner-Nordström naked singularities
Ruchi Mishra, Włodek Kluźniak
In general relativity, the asymptotically flat space-time of a charged, spherically symmetric (non-rotating) body is described by the Reissner-Nordström metric. This metric corresp…

Auroras on planets around pulsars
Ruchi Mishra, Miljenko Čemeljić, Jacobo Varela +1
The first extrasolar planets were discovered serendipitously, by finding the slight variation in otherwise highly regular timing of the pulses, caused by the planets orbiting a mil…
