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 Conditions of the Wide Binary Class 0 Protostars within BHR 71
John Tobin, Tyler Bourke, Stacy Mader +7
We present a characterization of the binary protostar system that is forming within a dense core in the isolated dark cloud BHR71. The pair of protostars, IRS1 and IRS2, are both i…
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…
Protostellar half-life: new methodology and estimates
L. E. Kristensen, M. M. Dunham
(Abridged) Protostellar systems evolve from prestellar cores, through the deeply embedded stage and then disk-dominated stage, before they end up on the main sequence. Knowing how…
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…
Evidence for the start of planet formation in a young circumstellar disk
Daniel Harsono, Per Bjerkeli, Matthijs H. D. van der Wiel +4
The growth of dust grains in protoplanetary disks is a necessary first step towards planet formation. This growth has been inferred via observations of thermal dust emission toward…
