| dc.description.abstract | All stars emit plasma outflows in every stage of their lives. The energy and velocity of these outflows change as a star shifts from accretion phase into a developed main-sequence star. In this thesis we discuss the effect of polytropic index on the energy of the stellar outflows. We first discuss the types of stellar outflows observed,their composition and the means by which they are ejected from the surface of the star. We also discuss the types of models that are used in mapping the outflows of stars in the literature review section. Further, we explain the hydrodyanmical model and present the governing equations for the case of one-fluid model. Lastly, we show results of using the polytropic model on plotting the velocity profile of the stellar wind and show that polytropic index has a great effect on the energy on the wind alongside which we also discuss the applications of this study. | |
