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 ÄemeljiÄ +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 ÄemeljiÄ +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 ÄemeljiÄ, WÅodek 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…
