is stable for fragmentation in a contracting disk, the adiabatic core often breaks into several fragments. Conditions for fragmentation and binary formation are studied. All the cores which show fragmentations are geometrically thin, as the diameter-to-thickness ratio is larger than 3. Two patterns

Accepted 2006 month day. Received year month day; Orbital angular momentum (Jo), systemic mass (M) and orbital period (P) distributions of chromospherically active binaries (CAB) and W Ursae Majoris (W UMa) systems were investigated. The diagrams of log Jo − log P, log M −log P and log Jo −log M

Received —; accepted — Abstract. We have investigated the effect of the number of primordial binaries on the relationship between the total number of detected binaries within globular cluster and its collision rate. We have used simulated populations of binary stars in globular clusters: primordial

Black holes in the universe have either masses less than about 20 M ⊙ (Orosz 2003), or masses exceeding about 10 6 M ⊙ (see Kormendy & Richstone, 1995, for some exceptions
