First detection of triply-deuterated methanol
B. Parise, A. Castets, E. Herbst +4
We report the first detection of triply-deuterated methanol, with 12 observed transitions, towards the low-mass protostar IRAS 16293-2422, as well as multifrequency observations of…
Mid-infrared spectral evidence for a luminous dust enshrouded source in Arp220
H. W. W. Spoon, A. F. M. Moorwood, D. Lutz +3
We have re-analyzed the 6-12 micron ISO spectrum of the ultra-luminous infrared galaxy Arp220 with the conclusion that it is not consistent with that of a scaled up version of a ty…
Search for solid HDO in low-mass protostars
B. Parise, T. Simon, E. Caux +4
We present ground-based 2.1 to 4.2 microns observations of four low-mass protostars. We searched for the 4.1 microns OD stretch band, characteristic of solid HDO in grain mantles.…
Detection of strongly processed ice in the central starburst of NGC4945
H. W. W. Spoon, A. F. M. Moorwood, K. M. Pontoppidan +4
The composition of ice grains provides an important tool for the study of the molecular environment of star forming regions. Using ISAAC at the VLT to obtain spectra around 4.65 mi…
The circumstellar envelope of the C-rich post-AGB star HD 56126
S. Hony, A. G. G. M. Tielens, L. B. F. M. Waters +1
We present a detailed study of the circumstellar envelope of the post-asymptotic giant branch ``21 micron object'' HD 56126. We build a detailed dust radiative transfer model of th…
