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…
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…
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…
