Gravitational self-lensing of Fast Radio Bursts in neutron star magnetospheres: I. The model

Simone Dall'Osso, Riccardo La Placa, Luigi Stella +2

Fast Radio Bursts (FRBs) are cosmological sub-second bursts of coherent radio emission, whose source is still unknown. To date, the galactic magnetar SGR 1935+2154 is the only astr…

Exploring higher order images with Fe K_α-lines from relativistic disks: black hole spin determination and bias

M. Falanga, P. Bakala, R. La Placa +3

We study the contributions to the relativistic Fe line profile from higher order images (HOIs) produced by strongly deflected rays from the disk which cross the plunging regi…

Three-dimensional general relativistic Poynting-Robertson effect. III. Static and non-spherical quadrupolar massive source

Vittorio De Falco, Pavel Bakala, Maurizio Falanga

We investigate the three-dimensional motion of a test particle in the gravitational field generated by a non-spherical compact object endowed with a mass quadrupole moment, describ…

Neutron Star Radius-to-mass Ratio from Partial Accretion Disc Occultation as Measured through Fe K Line Profiles

Riccardo La Placa, Luigi Stella, Alessando Papitto +5

We present a new method to measure the radius-to-mass ratio (R/M) of weakly magnetic, disc-accreting neutron stars by exploiting the occultation of parts of the inner disc by the s…

Habitable zones around almost extremely spinning black holes (black sun revisited)

Pavel Bakala, Jan Docekal, Zuzana Turonova

We analyzed the thermodynamics of hypothetical exoplanets at very low Keplerian circular orbits in close vicinity of rapidly spinning supermassive black holes. Such black hole exop…

Stable attractors in the three-dimensional general relativistic Poynting-Robertson effect

Vittorio De Falco, Pavel Bakala

We prove the stability of the critical hypersurfaces associated with the three-dimensional general relativistic Poynting-Robertson effect. The equatorial ring configures to be as a…
