What is the typical origin process for binary star systems?
Answer
They are born together from the same collapsing cloud of gas and dust
Binary stars generally share a common origin, forming simultaneously from the same collapsing cloud of gas and dust. As the cloud fragments and collapses, the law of conservation of angular momentum results in the creation of multiple dense cores. If these cores form in close proximity, they become gravitationally bound to one another. This shared beginning explains why binary stars often exhibit similar ages and chemical compositions.
