En l'an 1902, l'amour fou entre le jeune dreyfusard Valentin et la rebelle Thi Maï lance une saga aux destins tragiques qui va traverser l'Indochine, dans un Vietnam fascinant, de la conquête coloniale à la défaite. Leurs deux filles métisses, S

Context : Despite the low cosmic abundance of deuterium (D/H ~ 1e-5), large degrees of deuterium fractionation in molecules are observed in star forming regions with enhancements that can reach 13 orders of magnitude, which current models have diffic

We present observations of methanol lines in a sample of Class 0 low mass protostars. Using a 1-D radiative transfer model, we derive the abundances in the envelopes. In two sources of the sample, the observations can only be reproduced by the model

The HH 222 streamers in Orion and their associated non-thermal radio jet form a unique object, whose nature remains enigmatic. We have carried out a set of detailed millimeter observations around the non-thermal radio source in several transitions of

We present millimetre, optical, and near-infrared observations of M 16 in the vicinity of the Herbig-Haro ob- ject HH 216. The line profiles of the CO (J = 2−1) spectra are broad and consist of both emission originating from four warm molecular cor

While warm dense gas is prevalent around low-mass protostars, the presence of complex saturated molecules-the chemical inventory characteristic of hot cores-has remained elusive in such environments. Here we report the results of an IRAM 30 m study o

We present the results of a search for the doubly deuterated form of formaldehyde (D2CO) in a large sample of objects associated to star-formation. D2CO was detected in nearly 20 low-mass protostars, a success rate of 100%, with [D2CO]/[H2CO] abundan

We present ISO-LWS observations at high spectral resolution ($R \sim 10^{4}$) towards a cold molecular cloud in the line of sight of W49. The HD ground state transition at 112 μ m is detected, showing the first observation of this line in absorption
