Distinguishing Kerr naked singularities and black holes using the spin precession of a test gyro in strong gravitational fields
Chandrachur Chakraborty, Prashant Kocherlakota, Mandar Patil +3
We study here the precession of the spin of a test gyroscope attached to a stationary observer in the Kerr spacetime, specifically, to distinguish naked singularity (NS) from black…
Gravitomagnetic effect in magnetized neutron stars
Debarati Chatterjee, Chandrachur Chakraborty, Debades Bandyopadhyay
Rotating bodies in General Relativity produce frame dragging, also known as the {\it gravitomagnetic effect} in analogy with classical electromagnetism. In this work, we study the…
Spin precession in a black hole and naked singularity spacetimes
Chandrachur Chakraborty, Prashant Kocherlakota, Pankaj S. Joshi
We propose here a specific criterion to address the existence or otherwise of Kerr naked singularities, in terms of the precession of the spin of a test gyroscope due to the frame…
Frame-dragging Effect in Strong Gravity Regime
Chandrachur Chakraborty
The exact frame-dragging (or Lense-Thirring (LT) precession) rates for Kerr, Kerr-Taub-NUT (KTN) and Taub-NUT spacetimes have been derived. Remarkably, in the case of the `zero ang…
