Abstract:
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.
We have undertaken a spectroscopic survey of the central stars in PNe
to identify their spectral types.
We performed spectroscopic observations at low resolution with the 2-m
telescope at CASLEO, Argentina.
We present the spectra of 46 central stars of PNe, most of them are
OB-type and emission-line stars.
Description:
We observed 46 PNs using the 2.15m telescope at Casleo, Argentina,
between 2005 November and 2008 December.
