Ram pressure stripping(Gunn & Gott 1972), as quenching mechanism is found to be one of the main mechanisms in a cluster environment, but its importance in group and galaxy environments has been a subject of debate for several years. To differentiate between various quenching mechanisms in action along with ram pressure one needs theoretical models for ram pressure stripping (J.A. Hester 2006). We propose an analytical model to study ram pressure stripping as a mechanism of gas removal from galaxy disc in absence of any other process. We vary parameters related to ambient medium and galaxy to get a quantitative idea of their effects on the amount of gas that remains in galaxies. The results act as an upper bound on the amount of stripping that can happen due to ram pressure in various environments and hence the quenching of star formation. |
