Star Planet Interactions
Arghyadeep Paul, Kristina Kislyakova, Manuel Güdel +13
Star-planet interactions (SPIs) describe the continuous exchange of energy, momentum, and mass between exoplanets and their host stars through radiative, tidal, magnetic, and parti…
Planets in Pulsar Winds
T. Kaister, S. Andrés Joya Méndez, P. Marmat +4
Planets around pulsars were the first discovered exoplanets, found thanks to the extremely precise pulsar timing. Here we suggest that they could also be found through the radio em…
Strange quark star II: the minimal and maximal gravitational mass and the Keplerian configuration
Fatemeh Kayanikhoo, Mateusz Kapusta, Miljenko Čemeljić +2
We employ the MIT bag model with density-dependent bag constant for the equation of state (EOS) to estimate the gravitational mass and Keplerian frequency of rapidly rotating stran…
Strange quark star I: the maximum gravitational mass and deformation of magnetized spinning model
Fatemeh Kayanikhoo, Mateusz Kapusta, Miljenko Čemeljić +1
We investigate the structural parameters of strange quark stars (SQS) under the influence of strong magnetic fields and varying rotational frequencies. The equation of state is com…
Binary black holes in magnetized AGN disks
Raj Kishor Joshi, Aryan Bhake, Biswajit Banerjee +7
Stellar-mass binary black hole (BBH) mergers occurring within the disks of active galactic nuclei (AGN) are promising sources for gravitational waves detectable by the LIGO, Virgo,…
Magnetic precession as a model for QPOs in PULXs: flat-top noise ULXs are different
Miljenko Čemeljić, Włodek Kluźniak, Sukalpa Kundu
Context. Several instances of low frequency Quasi-Periodic Oscillations (QPOs) have been reported in ultraluminous X-ray sources (ULXs), including three in pulsating ones (PULXs) t…
Launching of asymmetric outflows from the star-disk magnetosphere
Miljenko Čemeljić, Aleksandra Kotek, Włodek Kluźniak
In resistive and viscous magnetohydrodynamical simulations, we obtain axial outflows launched from the innermost magnetosphere of a star-disk system. The launched outflows are foun…
Modulation of X-ray flux by obscuration of neutron star boundary layer
Gabriel Török, Kateřina Klimovičová, Debora Lančová +6
The quasi-periodic oscillations (QPOs) observed in the X-ray variability of both black hole (BH) and neutron star (NS) systems provide a tool for probing strong gravity and dense m…
Inner dusty regions of protoplanetary discs -- III. The role of non-radial radiation pressure in dust dynamics
Dejan Vinković, Miljenko Čemeljić
We explore dynamical behaviour of dust particles that populate the surface of inner optically thick protoplanetary discs. This is a disc region with the hottest dust and of a great…
General Relativistic Magnetohydrodynamic Simulations of Accreting Tori: Resolution Study
Angelos Karakonstantakis, Debora Lančová, Włodek Kluźniak +1
We present two-dimensional general relativistic radiative magnetohydrodynamical simulations of accretion disks around non-rotating stellar-mass black hole. We study the evolution o…
The maximum mass and deformation of rotating strange quark stars with strong magnetic fields
Fatemeh Kayanikhoo, Mateusz Kapusta, Miljenko Čemeljić
We study the structure and total energy of a strange quark star (SQS) endowed with a strong magnetic field with different rotational frequencies. The MIT bag model is used, with th…
Backflow in simulated MHD accretion disks
Ruchi Mishra, Miljenko Čemeljić, Wlodek Kluźniak
We perform resistive MHD simulations of accretion disk with alpha-viscosity, accreting onto a rotating star endowed with a magnetic dipole. We find backflow in the presence of stro…
Asymmetric Jet launching
Aleksandra Kotek, Miljenko Čemeljić, Włodek Kluźniak +1
In resistive and viscous magnetohydrodynamical (MHD) simulations we obtain axial jets launched from the innermost magnetosphere of a star-disk system. We found that in a part of th…
Backflow in Accretion Disk
Ruchi Mishra, Miljenko Čemeljić, Wlodek Kluźniak
Analytical solution for a thin hydrodynamic accretion disk shows that for some values of the viscosity parameter part of the accretion flow in the disk is not towards the star, but…
Transport of dust grain particles in the accretion disk
Robert Jaros, Miljenko Čemeljić, Włodek Kluźniak +2
Entrainment of dust particles in the flow inside and outside of the proto-planetary disk has implications for the disk evolution and composition of planets. Using quasi-stationary…
Towards pseudo-Newtonian black hole jets: comparison of forces
Maciej Jabłoński, Aleksandra Kotek, Miljenko Čemeljić +1
We perform resistive and viscous MHD simulations of axial jet launching from a magnetized thin accretion disk around a supermassive black hole. We compare the forces in our pseudo-…

Miljenko Čemeljić
Aims: I report results in numerical simulations of star-disk magnetospheric interaction. A thin accretion disk with corona above a rotating stellar surface is simulated in a parame…
