Radiation-hydrodynamics of star-disc collisions: From system parameters to outflows and lightcurves
Taj JankoviÄ, Sergey Karpov, Michal ZajaÄek +2
Quasi-periodic eruptions (QPEs) are nuclear transients producing bright, repeating soft X-ray flares superimposed on quiescent emission. A promising interpretation is that they are…
Evolution of Quasi-Periodic Eruptions in the post-TDE Accretion Disk Perturbed by an Orbiting Star
Martin Mondek, Michal ZajaÄek, Henry Best +3
Quasi-periodic eruptions (QPEs) are a recently discovered class of highly variable X-ray bursts originating in galactic nuclei. These high-amplitude bursts exhibit periodicity rang…
Tidal disruption of a low-mass star in an active galactic nucleus as the origin of the PS16dtm outburst
Marzena Åniegowska, Bożena Czerny, Michal ZajaÄek +7
The event PS16dtm, which occured in the center of the Narrow Line Seyfert 1 (NLS1) galaxy SDSS J015804.75-005221.8 (z = 0.080440), is one of the few candidates for a tidal disrupti…
Formation of stable exoplanetary systems around pulsars by capture: An exercise in computational classical mechanics
Václav PavlÃk, Steven N. Shore, VladimÃr Karas +1
The study of our Solar System -- its formation, evolution, and long-term stability -- has been ongoing for centuries and is now a standard part of scientific education. While the f…
Modulation of X-ray flux by obscuration of neutron star boundary layer
Gabriel Török, KateÅina KlimoviÄová, Debora LanÄová +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…
