Abstract: [eng] [cze]
Circumbinary disks consist of a pair of central bodies and a surrounding disk of gas. The exchange of angular momentum between the disk and the binary influences various aspects of the binary's evolution and plays an important role in the process of their merger. In this work, we collected and compared the results of various simulations of accretion and decretion disks, focusing primarily on the evolution of the binary separation under the influence of the disk. Furthermore, we simulate a decretion disk around a binary system using the DISCO code and compare its properties with the results of simulations of accretion disks. Cirkumbinárne disky sú zložené z dvojice centrálnych telies a disku plynu, ktorý ju obklopuje. Výmena momentu hybnosti medzi diskom a dvojicou má vplyv na rôzne aspekty života dvojice a veľký význam má aj na procese ich splynutia. V tejto práci sme zozbierali a porovnali výsledky rôznych simulácií akréčnych a dekréčnych diskov so zameraním hlavne na vývoj separácie dvojice vplyvom prítomnosti disku. Ďalej simulujeme dekréčny disk okolo dvojice telies pomocu kódu DISCO a porovnávame jeho javy a vlastnosti s výsledkami simulácií akréčnych diskov.
