Horizon Straddling ISCOs in Spherically Symmetric String Black Holes
Parthapratim Pradhan
The causal geodesics in the equatorial plane of a static extremal charged black holes in heterotic string theory are examined with regard to their geodesic stability, and compared…

Lense-Thirring Precession in Plebański-Demiański spacetimes
Chandrachur Chakraborty, Partha Pratim Pradhan
An exact expression of Lense-Thirring precession rate is derived for non-extremal and extremal Plebański-Demiański spacetimes. This formula is used to find the exact Lense-Thirring…
