Modeling the ortho-to-para abundance ratio of cyclic C3H2 in cold dense cores
In Hee Park, Valentine Wakelam, Eric Herbst
We report a detailed attempt to model the ortho-to-para abundance ratio of c-C3H2 so as to reproduce observed values in the cores of the well-known source TMC-1. According to obser…
Estimation and reduction of the uncertainties in chemical models: Application to hot core chemistry
Valentine Wakelam, Franck Selsis, Eric Herbst +1
It is not common to consider the role of uncertainties in the rate coefficients used in interstellar gas-phase chemical models. In this paper, we report a new method to determine b…
Chemical differentiation along the CepA-East outflows
C. Codella, R. Bachiller, M. Benedettini +3
We present the results of a multiline survey at mm-wavelengths of the Cepheus A star forming region. Four main flows have been identified: three pointing in the SW, NE, and SE dire…
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…
