Methanol emission from low mass protostars
S. Maret, C. Ceccarelli, A. G. G. M. Tielens +5
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 source…
Sulphur chemistry and molecular shocks: the case of NGC1333-IRAS2
Valentine Wakelam, Cecilia Ceccarelli, Alain Castets +5
We present SO and SO2 observations in the region of the low mass protostar IRAS2/NGC1333. The East-West outflow originating from this source has been mapped in four transitions of…
Densification of the International Celestial Reference Frame: Results of EVN Observations
P. Charlot, A. L. Fey, C. S. Jacobs +3
The current realization of the International Celestial Reference Frame (ICRF) comprises a total of 717 extragalactic radio sources distributed over the entire sky. An observing pro…
High-mass star formation in the Southern Hemisphere sky
V. Minier, M. G. Burton, T. Hill +4
We report on a multi-wavelength (IR to cm) and multi-resolution (1 mas to 20 arcsec) exploration of high-mass star formation regions in the Galactic plane, at longitudes observable…
Abundances and ages of the deconvolved thin/thick disks of the Galaxy
Pascal Girard, Caroline Soubiran
We have investigated the abundance of several chemical elements in two large stellar samples kinematically representative of the thin and the thick disks of the Galaxy. Chemical, k…
