Probing isotopic ratios at z = 0.89: molecular line absorption in front of the quasar PKS 1830-211
Sebastien Muller, Michel Guelin, Michael Dumke +2
With the Plateau de Bure interferometer, we have measured the C, N, O and S isotopic abundance ratios in the arm of a spiral galaxy with a redshift of 0.89. The galaxy is seen face…
C18O (3-2) observations of the Cometary Globule CG 12: a cold core and a C18O hot spot
L. K. Haikala, M. Juvela, J. Harju +3
The feasibility of observing the C18O (3-2) spectral line in cold clouds with the APEX telescope has been tested. As the line at 329.330 GHz lies in the wing of a strong atmospheri…
Detection of H2D+ in a massive prestellar core in Orion B
J. Harju, L. K. Haikala, K. Lehtinen +6
Aims. The purpose of this study is to examine the prediction that the deuterated H3+ ion, H2D+, can be found exclusively in the coldest regions of molecular cloud cores. This is al…
