International audience; Context: Comet C/2001 Q4 (NEAT) was extensively studied with the 1.1-m submillimetre telescope of the Odin satellite. The H2O line at 557 GHz was regularly observed from 6 March to 16 May 2004 and nearly continuously monitored

Autor: A. O. H. Olofsson, Aa. Sandqvist, Carina M. Persson, Marco Spaans, T. Liljestrom, Åke Hjalmarson, D. R. Poelman, John H. Black, Urban Frisk, Michael Olberg

Publikováno v: Astronomy & astrophysics, 494(2), 637-646. EDP Sciences

We have used the Odin satellite to obtain strip maps of the ground-state rotational transitions of ortho-water and ortho-ammonia, as well as CO(5-4) and 13CO(5-4) across the PDR, and H218O in the central position. A physi-chemical inhomogeneous PDR m

Since its launch in 2001, the Odin satellite has been observing the Galactic Centre Sgr A Complex (CND, +20 and +50 km s �1 Clouds) as well as the nearby star formation region, Sgr B2, a number of times. Observations have been made in the 118-119 G

Aims. The very high main beam efficiency (90%) of the telescope on the sub-millimetre wave satellite Odin, in combination with the small calibration errors in the absence of atmospheric attenuation, assures that observed line brightness temperatures

Submillimeter lines of H2O and NH3 have been detected in the carbon star IRC +10216 (CW Leo) with the Odin submillimeter satellite. The detection of the J = 110 → 101 557 GHz line of ortho-H2O confirms the earlier detection in the same source with

We present Odin observations of the AGB star W Hya in the ground-state transition of ortho-H2O, 1(10)-1(01), at 557GHz. The line is clearly of circumstellar origin. Radiative transfer modelling of the water lines observed by Odin and ISO results in a

Observations with the Odin mm/submm space telescope have been made towards the Sgr A Complex (the CircumNuclear Disk, the +20 and +50 km s–1molecular clouds) in the Galactic Centre and we report here on the results of searches for H2O2, H218O and o
