Gravitational-wave signatures of spinning particles around rotating hairy black holes
Surojit Dalui, Xian-Hui Ge
We study how the spin of a compact secondary and a gravitational-decoupling deformation of the Kerr geometry are imprinted on gravitational waves from strong-field eccentric motion…

Spin-Hair Induced Chaos of Spinning Test Particles in Rotating Hairy Black Holes
Surojit Dalui, Xian-Hui Ge
We investigate the finite-time instability of massive spinning test particles around a rotating hairy black hole generated through gravitational decoupling. The particle motion is…

Chaotic Dynamics in Extremal Black Holes: A Challenge to the Chaos Bound
Surojit Dalui, Chiranjeeb Singha, Krishnakanta Bhattacharya
We investigate chaotic dynamics in extremal black holes by analyzing the motion of massless particles in both Reissner-Nordström and Kerr geometries. Two complementary approaches (…
