Resumen
Context. There are more than 3000 confirmed and probably known Galactic planetary nebulae (PNe), but central star spectroscopic information is available for only 13% of them.
Aims. We have undertaken a spectroscopic survey of the central stars in PNe to identify their spectral types.
Methods. We performed spectroscopic observations at low resolution with the 2-m telescope at CASLEO, Argentina.
Results. We present the spectra of 46 central stars of PNe, most of them are OB-type and emission-line stars. Facultad de Ciencias Astronómicas y Geofísicas Instituto de Astrofísica de La Plata
