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…
PRODIGE - envelope to disk with NOEMA: V. Low 12C/13C ratios for CH3OH and CH3CN in hot corinos
L. A. Busch, J. E. Pineda, O. Sipilä +15
The 12C/13C isotope ratio has been derived towards numerous cold clouds (20-50 K) and a couple protoplanetary disks and exoplanet atmospheres. However, direct measurements of this…
Hunting pre-stellar cores with APEX: IRAS16293E (Oph464)
S. Spezzano, E. Redaelli, P. Caselli +7
Pre-stellar cores are the first steps in the process of star and planet formation. However, the dynamical and chemical evolution of pre-stellar cores is still not well understood.…
Impact of ice growth on the physical and chemical properties of dense cloud cores
O. Sipilä, P. Caselli, M. Juvela
We investigated the effect of time-dependent ice growth on dust grains on the opacity and hence on the dust temperature in a collapsing molecular cloud core, with the aim of quanti…
Role of NH3 Binding Energy in the Early Evolution of Protostellar Cores
S. Kakkenpara Suresh, O. Sipila, P. Caselli +1
NH(ammonia) plays a critical role in the chemistry of star and planet formation, yet uncertainties in its binding energy (BE) values complicate accurate estimates of its abun…
