Can accretion properties distinguish between a naked singularity, wormhole and black hole?
R. Kh. Karimov, R. N. Izmailov, A. A. Potapov +1
We first advance a mathematical novelty that the three geometrically and topologically distinct objects mentioned in the title can be exactly obtained from the Jordan frame vacuum…
String effect on the relative time delay in the Kerr-Sen black hole
R. N. Izmailov, R. Kh. Karimov, A. A. Potapov +1
A well known solution of heterotic string theory is the spinning Kerr-Sen black hole (KSBH) characterized by a string parameter . Kerr black hole is recovered at . The purp…
Accretion disks around the Gibbons-Maeda-Garfinkle-Horowitz-Strominger charged black holes
R. Kh. Karimov, R. N. Izmailov, Amrita Bhattacharya +1
It seems surprising that the emissivity properties of the accretion disk (\textit{à la} Page and Thorne) surrounding the Gibbons-Maeda-Garfinkle-Horowitz-Strominger (GMGHS) black h…
