Past analysis of HD 189733b's atmosphere has been a cause for some debate, with conflicting findings regarding water and sodium abundances and the presence of a high altitude haze. I will present our model of HD 189733b's cloud structure and atmospheric composition using VSTAR (Versatile Software for Transfer of Atmospheric Radiation ).   Since the effective temperature of the planet is expected to be approximately 5000K, newly available high-temperature spectral line lists were used. Our result will be compared to previous models and an assessment of the practicality of a model-focused approach to exoplanet spectral analysis will be made.
