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…
Exploring the Origins of Earth's Nitrogen: Astronomical Observations of Nitrogen-bearing Organics in Protostellar Environments
Thomas S. Rice, Edwin A. Bergin, Jes K. Jørgensen +1
It is not known whether the original carriers of Earth's nitrogen were molecular ices or refractory dust. To investigate this question, we have used data and results of Herschel ob…
The O/O ratio in Water in the Coma of Comet 67P / Churyumov-Gerasimenko measured with the Rosetta / ROSINA Double-Focusing Mass Spectrometer
Isaac R. H. G. Schroeder, Kathrin Altwegg, Hans Balsiger +11
The European Space Agency (ESA) spacecraft Rosetta accompanied the Jupiter-family comet (JFC) 67P / Churyumov-Gerasimenko for over two years along its trajectory through the inner…
The ALMA-PILS survey: Isotopic composition of oxygen-containing complex organic molecules toward IRAS 16293-2422B
J. K. Jørgensen, H. S. P. Müller, H. Calcutt +7
This paper presents a systematic survey of the deuterated and 13C isotopologues of a variety of oxygen-bearing complex organic molecules on Solar System scales toward the protostar…
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…
