The evolutionary evidence for Be/black hole binaries

Using Monte Carlo simulation of the modern scenario of the evolution of binary systems (the "Scenario Machine"), we calculate the number of binary black holes with Be stars and their expected observational properties. So far, only two possible candidates for Be/BH binaries have been proposed among the observable sources, the superluminal source GRS 1915+105 in the Galaxy and RX J0117.6-7330 in SMC. Using the "Scenario Machine" we obtained an evolutionary track that can lead to the formation of such systems. The modern evolutionary scenario predicts the existence of binary black holes on eccentric orbits around Be stars and such systems may be discovered in the near future.
