cds-question@unistra.frradio-sourcesWe 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.1995A&A...299..238Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/299/238CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/299/238https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/299/238http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/299/238https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/299/238https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/299/238http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/299/238GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/299/238/table1 (Far infrared data of the observed PN candidates in WSRT1 (Westerbork Synthesis Radio Telescope))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/299/238/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/299/238/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/299/238/table1?GETtext/xml+votable180.050000true16.73186364.2912580.005555555555555556Cone search capability for table J/A+A/299/238/table3 (Far infrared data of the observed PN candidates in WSRT2)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/299/238/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/299/238/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/299/238/table3?GETtext/xml+votable180.050000true16.3781664.716180.005555555555555556https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/299/238?format=asciiRadiodefaultJ/A+A/299/238/table1Far infrared data of the observed PN candidates in WSRT1 (Westerbork Synthesis Radio Telescope)TcColor temperatureKphys.temperatureintrecnoRecord number assigned by the VizieR team.
