The purpose of this project is to describe the central binary system of planetary nebula PHR J1510-6754 through binary modeling and spectral analysis from existing data. It is well known that the morphology of planetary nebulae is affected by binary central stars, and this system indeed is a binary system based on its light curve. No prior binary analysis has been completed thus far on the object. Spectral classification will allow for the binary modeling to have fewer variables by giving the temperature and limits on the radius of the cooler star in the system. The binary modeling will provide the values of the radii and mass of each star, the temperatures of both stars, the orbital period and inclination of the system. Analysis of both the binary modeling and the spectra of the system will also allow analysis of the distribution of the irradiation on the cool star, something that has not been done before experimentally.
