ALMA and ROSINA detections of phosphorus-bearing molecules: the interstellar thread between star-forming regions and comets
V. M. Rivilla, M. N. Drozdovskaya, K. Altwegg +11
To understand how Phosphorus-bearing molecules are formed in star-forming regions, we have analysed ALMA observations of PN and PO towards the massive star-forming region AFGL 5142…
Efficient Production of S in Interstellar Ices: The effects of cosmic ray-driven radiation chemistry and non-diffusive bulk reactions
Christopher N. Shingledecker, Thanja Lamberts, Jacob C. Laas +4
In this work, we reexamine sulfur chemistry occurring on and in the ice mantles of interstellar dust grains, and report the effects of two new modifications to standard astrochemic…
The first steps of Interstellar Phosphorus Chemistry
Johanna Chantzos, Victor M. Rivilla, Anton Vasyunin +4
Phosphorus-bearing species are an essential key to form life on Earth, however they have barely been detected in the interstellar medium. Since only PN and PO have been identified…
On Simulating the Proton-Irradiation of O and HO Ices Using Astrochemical-type Models, with Implications for Bulk Reactivity
Christopher N. Shingledecker, Anton Vasyunin, Eric Herbst +1
Many astrochemical models today explicitly consider the species that comprise the bulk of interstellar dust grain ice-mantles separately from those in the top few monolayers. Bomba…
The chemical structure of the very young starless core L1521E
Z. Nagy, S. Spezzano, P. Caselli +5
L1521E is a dense starless core in Taurus that was found to have relatively low molecular depletion by earlier studies, thus suggesting a recent formation. We aim to characterize t…
Efficient methanol production on the dark side of a prestellar core
Jorma Harju, Jaime E. Pineda, Anton I. Vasyunin +23
We present ALMA maps of the starless molecular cloud core Ophiuchus/H-MM1 in the lines of deuterated ammonia (ortho-NH2D), methanol (CH3OH), and sulphur monoxide (SO). The dense co…
