This research was conducted through the REU program at Cerro Tololo Interamerican Observatory in La Serena, Chile. For this research we reduced and modeled phase-resolved cyclotron spectroscopy of four AM Her stars: MN Hya, HU Aqu, VV Pup, and QS Tel. Two of the four spectra show good cyclotron harmonics while the other two were taken during a high state with too much noise in the spectra. Using a Constant-Lambda code (Schwope et al., 1990) we modeled the two good spectra and further modeled the harmonic motion of HU Aqr. The models produced for MN Hya gave parameters with a magnetic field strength between 44 MG and 43.4 MG, a plasma temperature between 4.1 keV and 5.6 keV, a log Λ of 4.2 ± 0.3, and a viewing angle set between 83.0 degrees and 70.0 degrees and HU Aqr a magnetic field between 36.0 MG and 37.6 MG, a plasma temperature between 15.0 keV and 15.5 keV, a log Λ of 4.0 ± 0.3, and a viewing angle between 89.5 degrees and 70.5 degrees. This was the first attempt to model MN Hya with a constant lambda code and the first harmonic motion model of HU Aqr.
