Abstract:
According to the current understanding stars are formed from dust molecular clouds (MCs) mostly from hydrogen gas interstellar medium (ISM). It is also believed that external agents like gravity shock-waves probably responsible to trigger to formation and evolution. Today, lot of attention has given to study the evolutionary scenario of stellar systems. This is partly in due as the result of both observational development and new computational techniques. But, still the analytical work is awaiting much to do to develop basic principles. To this end here we have analytically worked out on the evolution of mass transfers and their rates of evolution by assuming the standard three component interacting system: molecular clouds, atomic gases and stellar population and evolution. The results well agree with the earlier numerical works of the standard three-component system.
