Description
The formation of stars constitutes one of the basic problems of astrophysics. Understanding of star formation efficiency of molecular clouds (MCs) of a galaxy is necessary for studying the galactic evolution. Present data and theoretical formulations show that the structure and dynamics of the Galactic interstellar medium (ISM) are extremely complex. So that there is no simple model that can explain adequately the star formation efficiency of MCs because of its perplexing nature. The initial mass of the cloud needed for collapse varies based on the environment in which the cloud resides and the strength of its magnetic field, turbulence as well as the speed of rotation. In this paper, we estimate the star formation efficiency by combining predetermined models and the critical mass formulated by Kumssa and Tessema (2018).
