Radiative Transfer
Radiative transfer is concerned with the passage of photons through a stellar atmosphere. By applying radiative transfer techniques to analyze the spectrum of the star, we can determine the temperature, density, brightness, and chemical composition of a star. In my paper, we solved the transfer equation in plane-parallel geometry using a finite differencing technique. We considered the transfer equations for outgoing and incoming radiation, and manipulated the equations into the form of a tri-diagonal matrix. This matrix can be solve using Gaussian elimination. We used the resulting intensities and numerical quadrature to calculate the zeroeth order moment.
