Polarised radiative transfer

The polarised radiative transfer equations consist of four coupled first order differential equations in the four Stokes parameters which describe the radiation field. In the general case, one is dealing with a set of coupled integro-differential equations, and their solution can only be carried out by numerical methods. In simpler cases, analytical solutions are possible. The student will be required to review the theory behind the polarised transfer equations, and to discuss methods of solution currently used in the literature Some numerical work will be required.
