The Rate of Star Formation in Galaxies

Abstract

The physics of star formation that includes the processing agents and environmental conditions are fundamental issues in astrophysics. Observational data of nearby galaxies, over broad range of galactic environments and metallicities indicate that, star formation occurs mainly in the molecular phase of the interstellar medium (ISM). This star forming environmental correlation is currently being used in modeling variety of statistical techniques to estimate physical parameters. However, recent progress in the field also shows new observational discoveries including the dark matter & dark energy correlation to the phenomena. So there are more and more complications in understanding the large-scale star formation, one which incorporates our new understanding of the star formation within clouds and the ensemble properties of star formation in any galaxy including our own Milk-Way galaxy. So, with this motivation we raised the current 3-component interaction model of star forming system: Molecular cloud - Atomic gas - Active stellar evolution system. It is a simple realistic model that considers the physical interaction of the system that considers the standard physics we have at hand. With the recently raised computational concept we want for further analytical models and solutions how transfer process occurs between the system and how it influence the rate of formation. Comparing the theoretically generated result with that of observation, we found an encouraging result that shall be further investigated and adopted to progress the development of the field in the future.
