Infrared observations of candidate post-AGB transition objects
Published online by Cambridge University Press: 25 May 2016
Extract
In our search for new obscured PN, candidates were selected from the IRAS PSC based on their infrared colors that are typical for PN. These PN candidates were observed in the radio. On average 20 % of the objects were detected (Van de Steene & Pottasch: 1993, A&A 274, 895; 1995, A&A 299, 238). Optical spectroscopy showed that the PN candidates detected in the radio have emission line spectra typical of PN (Van de Steene et al. 1996a A&AS 118, 243; 1996b A&AS in press).
