Deuteration of HC3N and CH3CCH in the pre-stellar core L1544
K. Giers, S. Spezzano, Y. Lin +2
Deuterated molecules are a useful diagnostic tool to probe the evolution and the kinematics in the earliest stages of star formation. Due to the low temperatures and high densities…

Chemical segregation analysed with unsupervised clustering
K. Giers, S. Spezzano, Y. Lin +3
Molecular emission is a powerful tool for studying the physical and chemical structures of dense cores. The distribution and abundance of different molecules provide information on…

Fractionation in young cores: Direct determinations of nitrogen and carbon fractionation in HCN
S. S. Jensen, S. Spezzano, P. Caselli +4
We aim to determine the N/N and C/C ratios for HCN in six starless and prestellar cores and compare the results between the direct method using radiativ…
