Cosmological ideas in the 16th century
Hadrava, Petr; Hadravová, Alena
2003 - English
The influence of Giordano Bruno on extending the scope of early modern cosmology behing the borders of Solar system is studies, expecially the Kepler's thoughts on the limits of the Universe. V práci je studován vliv Giordana Bruna na rozšíření obzoru raně novověké kosmologie za hranice Sluneční soustavy, zejména Keplerovy úvahy o konečnosti vesmíru.

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.
