New detections of H2O masers in planetary nebulae and post-AGB stars using the Robledo-70 m antenna.

SUAREZ O., GOMEZ J.F. and MORATA O.

Abstract (from CDS):

We investigated the possible relationship between the evolutionary stage of post-AGB stars and planetary nebulae (PNe) and the presence of water masers in their envelopes We have used NASA's 70-m antenna in Robledo de Chavela (Spain) to search for the water maser transition at 22235.08MHz, towards a sample of 105 sources with IRAS colour characteristic of post-AGB stars and PNe at declination >-32°. 83% of the sources in the sample are post-AGB stars, 15% PNe or PN candidates, while only 2% seem to be HII regions. We have detected five water masers, of which four are reported for the first time: two in PNe (IRAS 17443-2949 and IRAS 18061-2505), a ``water fountain'' in a post-AGB star (IRAS 16552-3050), and one in a source previously catalogued as a PN, but whose classification is uncertain (IRAS 17580-3111). The unexpected detections of water masers in two objects among the small subset of PNe led us to suggest that the PNe harbouring water masers are a special type of massive, rapidly evolving PNe.
