The discussion revolves around the formation of X-ray binaries outside black holes, exploring the mechanisms of accretion and the structure of jets associated with these systems. It includes theoretical considerations and speculative questions regarding the nature of these astrophysical phenomena.
Participants present various aspects of the formation of X-ray binaries and the associated phenomena, but there is no consensus on the specifics of jet formation or the underlying mechanisms, indicating that multiple views and uncertainties remain in the discussion.
The discussion highlights the complexities and active research surrounding the formation of jets and the dynamics of accretion disks, with no definitive answers provided regarding these topics.
phyzguy said:Stars are formed in clusters, and a certain percentage of them end up in binaries. So a binary star system forms consisting of two main sequence stars. The more massive of the two main sequence stars evolves off the main sequence and collapses into a black hole. The other star is still a normal star and continues to orbit while the black hole pulls material from the normal star into an accretion disk around the black hole. The hot matter in the accretion disk emits X-rays, and you have an X-ray binary. The normal star and the accretion disk are all outside the event horizon.
Abtinnn said:Thank you for your response.
Also, why is the jet perpendicular to the plane of the accretion disk?
