Complex Organic Molecules in Protostars with ALMA Spectral Surveys (COMPASS) II. Approach to data reduction and products for line-rich broadband (sub)millimeter spectra
Adele L. Plunkett, Sébastien Maret, Daniel Harsono +26
Studying the chemical composition of the warm gas surrounding embedded solar-type protostars is one of the areas for which the Atacama Large Millimeter/submillimeter Array (ALMA) i…
The prebiotic molecular inventory of Serpens SMM1 I. An investigation of the isomers CHNCO and HOCHCN
N. F. W. Ligterink, A. Ahmadi, A. Coutens +6
Methyl isocyanate (CHNCO) and glycolonitrile (HOCHCN) are isomers and prebiotic molecules that are involved in the formation of peptide structures and the nucleobase ad…
The family of amide molecules toward NGC 6334I
Niels F. W. Ligterink, Samer J. El-Abd, Crystal L. Brogan +4
Amide molecules produced in space could play a key role in the formation of biomolecules on a young planetary object. However, the formation and chemical network of amide molecules…
Complex organic molecules in low-mass protostars on solar system scales -- I. Oxygen-bearing species
M. L. van Gelder, B. Tabone, Ł. Tychoniec +8
Complex organic molecules (COMs) are thought to form on icy dust grains in the earliest phase of star formation. The evolution of these COMs from the youngest Class 0/I protostella…
The ALMA-PILS survey: Inventory of complex organic molecules towards IRAS 16293-2422 A
S. Manigand, J. K. Jørgensen, H. Calcutt +6
Complex organic molecules (COM) are detected in many sources in the warm inner regions of envelopes surrounding deeply embedded protostars. Exactly how these COM form remains an op…
The ALMA-PILS survey: propyne (CHCCH) in IRAS 162932422
H. Calcutt, E. R. Willis, J. K. Jørgensen +7
Context. Propyne (CHCCH) has been detected in a variety of environments, from Galactic star-forming regions to extragalactic sources. Such molecules are excellent tracers of th…
Molecular complexity on disk-scales uncovered by ALMA: The chemical composition of the high-mass protostar AFGL 4176
Eva G. Bøgelund, Andrew G. Barr, Vianney Taquet +4
The chemical composition of high-mass protostars reflects the physical evolution associated with different stages of star formation. In this study, the molecular inventory of the f…
The ALMA-PILS survey: First detection of nitrous acid (HONO) in the interstellar medium
A. Coutens, N. F. W. Ligterink, J. -C. Loison +7
Nitrogen oxides are thought to play a significant role as a nitrogen reservoir and to potentially participate in the formation of more complex species. Until now, only NO, NO a…
Methylamine and other simple N-bearing species in the hot cores NGC 6334I MM1-3
E. G. Bøgelund, B. A. McGuire, M. R. Hogerheijde +2
In the search for the building blocks of life, nitrogen-bearing molecules are of particular interest since nitrogen-containing bonds are essential for the linking of amino acids an…
The ALMA-PILS survey: The first detection of doubly-deuterated methyl formate (CHD2OCHO) in the ISM
S. Manigand, H. Calcutt, J. K. Jørgensen +9
Studies of deuterated isotopologues of complex organic molecules can provide important constraints on their origin in regions of star formation. In particular, the abundances of de…
The formation of peptide-like molecules on interstellar dust grains
N. F. W. Ligterink, J. Terwisscha van Scheltinga, V. Taquet +4
Molecules with an amide functional group resemble peptide bonds, the molecular bridges that connect amino acids, and may thus be relevant in processes that lead to the formation of…
The ALMA-PILS survey: Stringent limits on small amines and nitrogen-oxides towards IRAS 16293-2422B
N. F. W. Ligterink, H. Calcutt, A. Coutens +8
Hydroxylamine (NHOH) and methylamine (CHNH) have both been suggested as precursors to the formation of amino acids and are therefore of interest to prebiotic chem…
Methanol ice co-desorption as a mechanism to explain cold methanol in the gas-phase
N. F. W. Ligterink, C. Walsh, R. G. Bhuin +3
Methanol is formed via surface reactions on icy dust grains. Methanol is also detected in the gas-phase at temperatures below its thermal desorption temperature and at levels highe…
