Complex Organic Molecules in Protostars with ALMA Spectral Surveys (COMPASS): I. Overview of the ALMA Large Program
J. K. Jørgensen, A. Coutens, M. N. Drozdovskaya +27
It remains a fundamental research question in astrochemistry to characterize the inventory of complex organic molecules formed during the early stages of star formation, which may…
Complex Organic Molecules in Protostars with ALMA Spectral Surveys (COMPASS) III. CHOH isotopic fractionation in the low-mass protostar BHR71-IRS1
A. Coutens, F. Cruz-Sáenz de Miera, J. K. Jørgensen +26
[Abridged] Methanol is a complex organic molecule detected in both ice and gas toward star-forming regions. Due to its high abundance, its rarer isotopologues, including the deuter…
CoCCoA: Complex Chemistry in hot Cores with ALMA. Selected oxygen-bearing species
Y. Chen, M. L. van Gelder, P. Nazari +22
Complex organic molecules (COMs) have been observed to be abundant in the gas phase toward protostars. Deep line surveys have been carried out only for a limited number of well-kno…
An overview of desorption parameters of Volatile and Complex Organic Molecules: A systematic dig on experimental literature
N. F. W. Ligterink, M. Minissale
Many molecules observed in the interstellar medium are thought to result from thermal desorption of ices. Parameters such as desorption energy and pre-exponential frequency factor…
N-bearing complex organics toward high-mass protostars: Constant ratios pointing to formation in similar pre-stellar conditions across a large mass range
P. Nazari, J. D. Meijerhof, M. L. van Gelder +10
No statistical study of COMs toward a large sample of high-mass protostars with ALMA has been carried out so far. We aim to study six N-bearing species: CHCN, HNCO, NHCHO,…
Predicting binding energies of astrochemically relevant molecules via machine learning
Torben Villadsen, Niels F. W. Ligterink, Mie Andersen
The behaviour of molecules in space is to a large extent governed by where they freeze out or sublimate. The molecular binding energy is thus an important parameter for many astroc…
The prebiotic molecular inventory of Serpens SMM1: II. The building blocks of peptide chains
Niels F. W. Ligterink, Aida Ahmadi, Bijaya. Luitel +7
This work aims to constrain the abundances of interstellar amides, by searching for this group of prebiotic molecules in the intermediate-mass protostar Serpens SMM1-a. ALMA observ…
Complex organic molecules in low-mass protostars on Solar System scales -- II. Nitrogen-bearing species
P. Nazari, M. L. van Gelder, E. F. van Dishoeck +10
The chemical inventory of planets is determined by the physical and chemical processes that govern the early phases of star formation. The aim is to investigate N-bearing complex o…
The ALMA-PILS survey: first detection of methyl isocyanide (CHNC) in a solar-type protostar
H. Calcutt, M. R. Fiechter, E. R. Willis +9
Methyl isocyanide (CHNC) is the isocyanide with the largest number of atoms confirmed in the interstellar medium (ISM), but it is not an abundant molecule, having only been det…
Linking interstellar and cometary O: a deep search for OO in the solar-type protostar IRAS 16293--2422
Vianney Taquet, Ewine F. van Dishoeck, Matthew Swayne +15
Recent measurements carried out at comet 67P/C-G with the probe revealed that molecular oxygen, O, is the fourth most abundant molecule in comets. Models show t…
Low levels of methanol deuteration in the high-mass star-forming region NGC 6334I
Eva G. Bøgelund, Brett A. McGuire, Niels F. W. Ligterink +6
The abundance of deuterated molecules in a star-forming region is sensitive to the environment in which they are formed. Deuteration fractions therefore provide a powerful tool for…
UV photodesorption of methanol in pure and CO-rich ices: desorption rates of the intact molecule and of the photofragments
Mathieu Bertin, Claire Romanzin, Mikhail Doronin +6
Wavelength dependent photodesorption rates have been determined using synchrotron radiation, for condensed pure and mixed methanol ice in the 7 -- 14 eV range. The VUV photodesorpt…
