Ortho-to-para ratio of interstellar heavy water
C. Vastel, C. Ceccarelli, E. Caux +65
Despite the low elemental deuterium abundance in the Galaxy, enhanced molecular D/H ratios have been found in the environments of low-mass star forming regions, and in particular t…
Physical structure of the envelopes of intermediate-mass protostars
N. Crimier, C. Ceccarelli, T. Alonso-Albi +11
Context: Intermediate mass protostars provide a bridge between low- and high-mass protostars. Furthermore, they are an important component of the UV interstellar radiation field. 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 solar type protostar IRAS16293-2422: new constraints on the physical structure
Nicolas Crimier, Cecilia Ceccarelli, Sebastien Maret +5
Context: The low mass protostar IRAS16293-2422 is a prototype Class 0 source with respect to the studies of the chemical structure during the initial phases of life of Solar type s…
Physical structure and water line spectrum predictions of the Intermediate Mass protostar OMC2-FIR4
N. Crimier, C. Ceccarelli, B. Lefloch +1
Aims. Intermediate Mass (IM) stars are an important component of our Galaxy, as they significantly contribute to the interstellar FUV field and, consequently, play an important rol…
