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…
The distribution of maser stars in the inner Milky Way: the effect of a weak, rotating bar
H. J. Habing, M. N. Sevenster, M. Messineo +4
We derive the distribution of maser stars in the inner Milky Way (MW) based on an analysis of lV-diagrams (lVd) for two samples of maser stars: 771 OH/IR stars and 363 SiO-maser st…
OH-selected AGB and post-AGB stellar objects II.Blue versus red evolution off the AGB
Maartje Sevenster
Using objects found in a systematic survey of the galactic Plane in the 1612-MHz OH line, we discuss in detail two ``sequences'' of post-AGB evolution, a red and a blue. We argue t…
OH-selected AGB and post-AGB objects I.Infrared and maser properties
Maartje Sevenster
Using 766 compact objects from a survey of the galactic Plane in the 1612-MHz OH line, new light is cast on the infrared properties of evolved stars on the TP-AGB and beyond. The u…
An inner ring and the micro lensing toward the Bulge
M. Sevenster, A. Kalnajs
All current Bulge-Disk models for the inner Galaxy fall short of reproducing self-consistently the observed micro-lensing optical depth by a factor of two (). We show that th…
The ATCA/VLA OH 1612 MHz survey. III. Northern Galactic Plane
M. Sevenster, H. v. Langevelde, R. Moody +3
We present observations of the region between 5deg < l < 45deg and |b| < 3deg, in the OH 1612 MHz line, taken from 1993 to 1995 with the VLA. These observations are the last part o…
