Stellar transits across a magnetized accretion torus as a mechanism for plasmoid ejection
Petra Suková, Michal Zajaček, Vojtěch Witzany +1
The close neighbourhood of a supermassive black hole contains not only the accreting gas and dust but also stellar-sized objects, such as late-type and early-type stars and compact…
Perturbing the accretion flow onto a supermassive black hole by a passing star
Petra Suková, Michal Zajaček, Vojtěch Witzany +1
The close neighbourhood of a supermassive black hole contains not only accreting gas and dust, but also stellar-sized objects like stars, stellar-mass black holes, neutron stars, a…
Missing bright red giants in the Galactic center: A fingerprint of its once active state?
Michal Zajaček, Anabella Araudo, Vladimír Karas +5
In the Galactic center nuclear star cluster, bright late-type stars exhibit a flat or even a decreasing surface-density profile, while fainter late-type stars maintain a cusp-like…
Free motion around black holes with discs or rings: between integrability and chaos -- V
L. Polcar, P. Suková, O. Semerák
Complete integrability of geodesic motion, the well known feature of the fields of isolated stationary black holes, can easily be "spoilt" by the presence of some additional source…
Shocks in the relativistic transonic accretion with low angular momentum
Petra Suková, Szymon Charzyński, Agnieszka Janiuk
We perform 1D/2D/3D relativistic hydrodynamical simulations of accretion flows with low angular momentum, filling the gap between spherically symmetric Bondi accretion and disc-lik…
Non-linear behaviour of XTE J1550-564 during its 1998-1999 outburst, revealed by recurrence analysis
Petra Suková, Agnieszka Janiuk
We study the X-ray emission of the microquasar XTE J1550-564 and analyze the properties of its light curves using the recurrence analysis method. The indicators for non-linear dyna…
