Observational signature of a near-extremal Kerr-Sen black hole in the heterotic string theory
Minyong Guo, Shupeng Song, Haopeng Yan
We analytically study the optical appearance of an isotropically emitter orbiting near the horizon of a near-extremely rotating Kerr-Sen (KS) black hole which is an electrically ch…
