A large (~1 pc) contracting envelope around the prestellar core L1544

E. Redaelli, A. Chacón-Tanarro, P. Caselli +4

Prestellar cores, the birthplace of Sun-like stars, form from the fragmentation of the filamentary structure that composes molecular clouds, from which they must inherit at least p…

Chemistry and dynamics of the prestellar core L1544

O. Sipilä, P. Caselli, E. Redaelli +1

We aim to quantify the effect of chemistry on the infall velocity in the prestellar core L1544. Previous observational studies have found evidence for double-peaked line profiles f…

A Survey of Deuterated Ammonia in the Cepheus Star-Forming Region L1251

Maria Galloway-Sprietsma, Yancy L. Shirley, James Di Francesco +4

Understanding the chemical processes during starless core and prestellar core evolution is an important step in understanding the initial stages of star and disk formation. This pr…

Deuteration of c-CH towards the pre-stellar core L1544

K. Giers, S. Spezzano, F. Alves +7

Context: In the centre of pre-stellar cores, the deuterium fractionation is enhanced due to the cold temperatures and high densities. Therefore, the chemistry of deuterated molecul…

An Interferometric View of H-MM1. I. Direct Observation of NH3 Depletion

Jaime E. Pineda, Jorma Harju, Paola Caselli +14

Spectral lines of ammonia, NH, are useful probes of the physical conditions in dense molecular cloud cores. In addition to advantages in spectroscopy, ammonia has also been sug…

The Central 1000 au of a Pre-stellar Core Revealed with ALMA. II. Almost Complete Freeze-out

Paola Caselli, Jaime E. Pineda, Olli Sipilä +18

Pre-stellar cores represent the initial conditions in the process of star and planet formation. Their low temperatures (10 K) allow the formation of thick icy dust mantles, whic…
