High angular resolution observations towards OMC-2 FIR 4: Dissecting an intermediate-mass protocluster
A. López-Sepulcre, V. Taquet, Á. Sánchez-Monge +9
OMC-2 FIR 4 is one of the closest known young intermediate-mass protoclusters, located at a distance of 420 pc in Orion. This region is one of the few where the complete 500-2000 G…
Herschel CHESS discovery of the fossil cloud that gave birth to the Trapezium and Orion KL
Ana López-Sepulcre, Mihkel Kama, Cecilia Ceccarelli +4
As part of the Herschel Guaranteed Time Key Programme CHESS, we present the discovery of a diffuse gas component in the foreground of the intermediate-mass protostar OMC-2 FIR 4, l…
First detection of ND in the solar-mass protostar IRAS16293-2422
A. Bacmann, E. Caux, P. Hily-Blant +64
In the past decade, much progress has been made in characterising the processes leading to the enhanced deuterium fractionation observed in the ISM and in particular in the cold, d…
Chemical study of intermediate-mass (IM) Class 0 protostars. CO depletion and N2H+ deuteration
T. Alonso-Albi, A. Fuente, N. Crimier +10
We are carrying out a physical and chemical study of the protostellar envelopes in a representative sample of IM Class 0 protostars. In our first paper (Crimier et al. 2010), we de…
The Distribution of Ortho-H_2D+(1_1,0 - 1_1,1) in L1544: Tracing the Deuteration Factory in Prestellar Cores
C. Vastel, P. Caselli, C. Ceccarelli +5
Prestellar cores are unique laboratories for studies of the chemical and physical conditions preceding star formation. We observed the prestellar core L1544 in the fundamental tran…
H_2D^+: a light on baryonic dark matter?
Cecilia Ceccarelli, Carsten Dominik
It has been suggested that the dark halos of galaxies are constituted by cloudlets of cold (< 10 K) H_2 and dense (> 10^7$ cm^{-3}) molecular gas. Such gas is extremely difficult t…
