2021 superoutburst of WZ Sge-type dwarf nova V627 Pegasi lacks an early superhump phase
Yusuke Tampo, Taichi Kato, Naoto Kojiguchi +27
Superoutbursts in WZ Sge-type dwarf novae (DNe) are characterized by both early superhumps and ordinary superhumps originating from the 2:1 and 3:1 resonances, respectively. Howeve…
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…
Three-dimensional general relativistic Poynting-Robertson effect II: Radiation field from a rigidly rotating spherical source
Pavel Bakala, Vittorio De Falco, Emmanuele Battista +4
We investigate the three-dimensional, general relativistic Poynting-Robertson effect in the case of rigidly rotating spherical source which emits radiation radially in the local co…
The three-dimensional general relativistic Poynting-Robertson effect I: radial radiation field
Vittorio De Falco, Pavel Bakala, Emmanuele Battista +3
In this paper we investigate the three-dimensional (3D) motion of a test particle in a stationary, axially symmetric spacetime around a central compact object, under the influence…
On the properties of slow mhd sausage waves within small-scale photospheric magnetic structures
N. Freij, I. Dorotovic, R. J. Morton +3
The presence of magneto-acoustic waves in magnetic structures in the solar atmosphere is well-documented. Applying the technique of solar magneto-seismology (SMS) allows us to infe…
On standing sausage waves in photospheric magnetic waveguides
I. Dorotovic, R. Erdelyi, N. Freij +2
By focusing on the oscillations of the cross-sectional area and the intensity of magnetic waveguides located in the lower solar atmosphere, we aim to detect and identify magnetohyd…
