Long-term activity of the X-ray source QR And / RX J0019.8+2156
Šimon, Vojtěch; Sobotka, P.; Marek, P.; Lehký, M.; Šmelcer, L.; Lomoz, Fr.
2002 - English QR And has been monitored in the framework of the observational campaing which started in 1998. The authors resolved prominent variations of the orbital modulation which depend on the state of the long-term activity of the system.

Formation of eccentric disks around black holes
Hadrava, Petr; Řezáč, R.; Oestgaard, E.
2001 - English The formation and evolution of eccentric disks around black holes due to explosion of a companion on an eccetric orbit is modeled by means of exact general-relativistic N-particle treatment. It is shown that in spite of the generally accepted view that the debris must be quickly smeared out to a circular accretion disk. Keywords: black holes; accretion disks; eccentric rings Available at various institutes of the ASCR Formation of eccentric disks around black holes
