In our quest to understand the shaping mechanisms of planetary nebulae, we have modeled the known binary central star Hf 2-2. The models have been matched to photometric variation data in B, V and R filters. Our goal was to constrain as much as possible the fundamental properties of the binary system: the masses, temperatures, and radii of each star as well as the inclination angle of the system. These constrained system properties, especially the inclination angle, can then be compared with the predictions of the theory that binary stars are responsible for the complex shapes we see in planetary nebulae. The inclination angle for Hf 2-2 has been constrained to the range of 25°-55°. From visual inspection of the nebula, the inclination angle range of Hf 2-2 includes alignment with the nebula, though thorough modeling of the nebular structure is necessary to draw an unambiguous conclusion.
