H2O Maser Polarization of the Water Fountains IRAS 15445-5449 and IRAS 18043-2116

A. F. Pérez-Sánchez, W. H. T. Vlemmings, J. M. Chapman

We present the morphology and linear polarization of the 22-GHz H2O masers in the high-velocity outflow of two post-AGB sources, d46 (IRAS 15445-5449) and b292 (IRAS 18043-2116). T…

H2O Maser Observations of Candidate Post-AGB Stars and Discovery of Three High-velocity Water Sources

R. M. Deacon, J. M. Chapman, A. J. Green +1

We present the results of 22 GHz H_2O maser observations of a sample of 85 post-Asymptotic Giant Branch (post-AGB) candidate stars, selected on the basis of their OH 1612 MHz maser…

HO maser emission from bright rimmed clouds in the northern hemisphere

R. Valdettaro, F. Palla, J. Brand +1

We report the results of a multi-epoch survey of water maser observations at 22.2 GHz with the Medicina radiotelescope from 44 bright rimmed clouds (BRCs) of the northern hemispher…

Non-thermal radio emission from O-type stars. I. HD 168112

R. Blomme, S. Van Loo, M. De Becker +4

We present a radio lightcurve of the O5.5 III(f+) star HD 168112, based on archive data from the Very Large Array (VLA) and the Australia Telescope Compact Array (ATCA). The fluxes…

A Circular Planetary Nebula around the OH/IR Star OH 354.88-0.54 (V1018 Sco)

Martin Cohen, Quentin A Parker, Jessica Chapman

New deep, high-resolution H-alpha imagery from the UK Schmidt Telescope (UKST) Unit's H-alpha survey of the Southern Galactic Plane reveals the presence of a faint, highly circular…

Bipolar outflows in OH/IR stars

Albert A. Zijlstra, J. M. Chapman, P. te Lintel Hekkert +5

We investigate the development of bipolar outflows during the early post-AGB evolution. A sample of ten OH/IR stars is observed at high angular resolution, including bipolar nebula…
