31 Dec 1998 | | Journal: | Astron. Zh. 1999, v.76, p.270 (Astron. Reports v.43, p.229) | | Subject: | astro-ph | | Affiliation: | Institute of Astronomy of the Russian Acad. of Sci., Moscow; Keldysh Institute of Applied Mathematics, Moscow | | Abstract: | We present the results of three-dimensional numerical simulations of mass transfer in semi-detached binary systems in which the mass-losing star is rotating. The cases of aligned and misaligned non-synchronous rotation of the donor star are considered; the resulting flow patterns are compared to the synchronous case. The main properties of the flow, such as the formation of an circumbinary envelope, the absence of a "hot spot" on the edge of the accretion disk, and the formation of a shock wave along the flow edge, are qualitatively similar to those obtained earlier. For the case of misaligned, non-synchronous rotation, the behavior of the disk and surrounding matter in established flow regime reflects changes in the boundary conditions at the surface of the donor star; in other words, a "driven disk" model is realized in the calculations. | | Source: | arXiv, astro-ph/9812484 | | Services: | Forum | Review | PDF | Favorites | |
