Title: | Central Stars of Planetary Nebulae: Survey for Spectral Classification |

Abstract
Currently, ~3000 Planetary Nebulae are catalogued in our Galaxy. Only 16% have spectroscopic information of their central-stars (CSPN). CSPN constitutes an heterogeneous group, most with H-rich atmospheres but an important fraction with H-deficient atmospheres. The origin and evolution of Hdeficient CSPN remain poorly understood. To characterize the stellar population of CSPN is necessary to obtain more spectroscopic data. We propose to obtain long-slit GMOS data to perform the spectral classification of eight CSPN.
