SiO and CH3CCH abundances and dust emission in high-mass star-forming cores
O. Miettinen, J. Harju, L. K. Haikala +1
Aims. The main goal of the present study is to determine the fractional SiO abundance in high-mass star-forming cores, and to investigate its dependence on the physical conditions.…
HCN and HNC mapping of the protostellar core Cha-MMS1
P. P. Tennekes, J. Harju, M. Juvela +1
Aims. The purpose of this study is to investigate the distributions of the isomeric molecules HCN and HNC and estimate their abundance ratio in the protostellar core Cha-MMS1 locat…
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…
