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.
