Abstract:
We analyzed radio continuum observations of unidentified IRAS point
sources with far IR colors that are typical of planetary nebulae.
These IRAS-selected planetary nebula candidates are located outside
the galactic bulge and were observed with the Westerbork Radio
Synthesis Telescope. We have detected 20 new planetary nebulae out of
82 observed candidates. The detected sources are very close to the
galactic plane. The detection rate is highest in that part of the
color-color diagram, where planetary nebulae are expected to spend
most time during their evolution. The radio and IR properties are
compared with PN detected in the same way in the galactic bulge and
with optical planetary nebulae which fulfill the same selection
criteria. On average, the IR excess of the IRAS-selected and radio
detected planetary nebula candidates is higher than for the optical
planetary nebulae.
