Abstract

In this paper, a gas sphere model of weak-line classical T Tauri stars is investigated based on the Enhanced Variational Iteration Method (EVIM) and the Boubaker Polynomials Expansion Scheme (BPES). Solutions for the implemented second-order differential equations are obtained and quantitatively analyzed. The analytical results reveal many interesting features of the main patterns of accretion disks found in some relevant published studies.
