Combined model for , , and spin-state chemistry in molecular clouds
O. Sipilä, L. Colzi, E. Roueff +3
We present a new gas-grain chemical model for the combined isotopic fractionation of carbon and nitrogen in molecular clouds, in which the isotope chemistry of carbon and nitrogen…
Modelling Deuterated Isotopologues of Methanol toward the Pre-Stellar Core L1544
W. Riedel, O. Sipilä, E. Redaelli +4
Aims. We aim to improve a previous model for the prediction of column densities and deuterium fractions of non- and singly deuterated methanol. Thereby, we try to identify crucial…
Similar levels of deuteration in the pre-stellar core L1544 and the protostellar core HH211
K. Giers, S. Spezzano, P. Caselli +6
In the centre of pre-stellar cores, deuterium fractionation is enhanced due to the low temperatures and high densities. Therefore, the chemistry of deuterated molecules can be used…
First detection of deuterated methylidyne (CD) in the interstellar medium
Arshia M. Jacob, Karl M. Menten, Friedrich Wyrowski +1
While the abundance of elemental deuterium is relatively low (D/H ~ a few 1E-5), orders of magnitude higher D/H abundance ratios have been found for many interstellar molecules, en…
