Circumstellar water vapour in M-type AGB stars: Constraints from H2O(1_10 - 1_01) lines obtained with Odin
M. Maercker, F. L. Schoeier, H. Olofsson +8
Aims: Spectrally resolved circumstellar H2O(1_10 - 1_01) lines have been obtained towards three M-type AGB stars using the Odin satellite. This provides additional strong constrain…
Circumstellar water vapour in M-type AGB stars: Radiative transfer models, abundances and predictions for HIFI
Matthias Maercker, Fredrik L. Schoeier, Hans Olofsson +2
Aims: By performing a detailed radiative transfer analysis, we determine fractional abundances of circumstellar H2O in the envelopes around six M-type asymptotic giant branch stars…
Embedded Stellar Populations towards Young Massive Star Formation Regions I. G305.2+0.2
S. N. Longmore, M. Maercker, S. Ramstedt +1
We present deep, wide-field J, H and Ks images taken with IRIS2 on the Anglo Australian Telescope, towards the massive star formation region G305.2+0.2. Combined with 3.6, 4.5, 5.8…
L-band (3.5 micron) IR-excess in massive star formation, II. RCW 57/NGC 3576
M. Maercker, M. G. Burton, C. M. Wright
We present a JHKL survey of the massive star forming region RCW 57 (NGC 3576) based on L-band data at 3.5 micron taken with SPIREX (South Pole Infrared Explorer), and 2MASS JHK dat…
L-band (3.5 micron) IR-excess in massive star formation, I. 30 Doradus
M. Maercker, M. G. Burton
L-band data of 30 Doradus at 3.5 micron taken with SPIREX (South Pole Infrared Explorer) is presented. The photometry was combined with 2MASS JHK data at 1.25-2.2 micron. Colour-co…
