Investigation of the rotational spectrum of CDOD and an astronomical search toward IRAS 162932422
V. V. Ilyushin, H. S. P. Müller, J. K. Jørgensen +8
Solar-type prestellar cores and protostars display large amounts of deuterated organic molecules. Recent findings on CHDOH and CDOH toward IRAS 16293-2422 suggest that even…
Rotation-tunneling spectrum and astrochemical modeling of dimethylamine, CHNHCH, and searches for it in space
H. S. P. Müller, R. T. Garrod, A. Belloche +6
Methylamine has been the only simple alkylamine detected in the interstellar medium for a long time. With the recent secure and tentative detections of vinylamine and ethylamine, r…
LLWP -- A new Loomis-Wood Software at the Example of Acetone-13C1
Luis Bonah, Oliver Zingsheim, Holger S. P. Müller +3
Acetone-13C1 is a complex organic molecule with two internal methyl (-CH3) rotors having relatively low effective barriers to internal rotation of about 249 cm-1. This leads to two…
Millimeter wave spectrum and search for vinyl isocyanate toward Sgr B2(N) with ALMA
K. Vávra, L. Kolesniková, A. Belloche +9
The interstellar detections of isocyanic acid, methyl isocyanate, and very recently also ethyl isocyanate, open the question of the possible detection of vinyl isocyanate in the in…
Resolving desorption of complex organic molecules in a hot core: Transition from non-thermal to thermal desorption or two-step thermal desorption?
Laura A. Busch, Arnaud Belloche, Robin T. Garrod +2
Using the high angular resolution provided by the ALMA interferometre we want to resolve the COM emission in the hot molecular core Sagittarius B2(N1) and thereby shed light on the…
Rotational spectroscopy -propanol: and conformers
O. Zingsheim, J. Maßen, H. S. P. Müller +6
The primary alcohol -propanol (i.e., -propanol or propan-1-ol; CHOH) occurs in five different conformers: , , , , and . All rotational spect…
Interstellar detection and chemical modeling of iso-propanol and its normal isomer
A. Belloche, R. T. Garrod, O. Zingsheim +2
The detection of a branched alkyl molecule in the high-mass star forming protocluster Sgr B2(N) permitted by the advent of ALMA revealed a new dimension of interstellar chemistry.…
Rotational and rovibrational spectroscopy of CDOH with an account of CDOH toward IRAS 162932422
V. V. Ilyushin, H. S. P. Müller, J. K. Jørgensen +10
Solar-type protostars harbor highly deuterated complex organics. While this degree of deuteration may provide important clues in studying the formation of these species, spectrosco…
The ALMA-PILS survey: Formaldehyde deuteration in warm gas on small scales toward IRAS 16293-2422 B
M. V. Persson, J. K. Jørgensen, H. S. P. Müller +7
[abridged] The enhanced degrees of deuterium fractionation observed in envelopes around protostars demonstrate the importance of chemistry at low temperatures, relevant in pre- and…
The ALMA-PILS survey: Detection of CHNCO toward the low-mass protostar IRAS 16293-2422 and laboratory constraints on its formation
N. F. W. Ligterink, A. Coutens, V. Kofman +7
Methyl isocyanate (CHNCO) belongs to a select group of interstellar molecules considered to be relevant precursors in the formation of larger organic compounds, including tho…
The ALMA-PILS survey: First detections of ethylene oxide, acetone and propanal toward the low-mass protostar IRAS 16293-2422
J. M. Lykke, A. Coutens, J. K. Jørgensen +14
One of the open questions in astrochemistry is how complex organic and prebiotic molecules are formed. Aims. Our aim is to start the process of compiling an inventory of oxygen-bea…
The ALMA-PILS survey: First detections of deuterated formamide and deuterated isocyanic acid in the interstellar medium
A. Coutens, J. K. Jørgensen, M. H. D. van der Wiel +15
Formamide (NHCHO) has previously been detected in several star-forming regions and is thought to be a precursor for different prebiotic molecules. Its formation mechanism is st…
Herschel observations of EXtra-Ordinary Sources (HEXOS): Observations of H2O and its isotopologues towards Orion KL
G. J. Melnick, V. Tolls, D. A. Neufeld +49
We report the detection of more than 48 velocity-resolved ground rotational state transitions of H2(16)O, H2(18)O, and H2(17)O - most for the first time - in both emission and abso…
Reversal of infall in SgrB2(M) revealed by Herschel/HIFI observations of HCN lines at THz frequencies
Rainer Rolffs, Peter Schilke, Claudia Comito +54
To investigate the accretion and feedback processes in massive star formation, we analyze the shapes of emission lines from hot molecular cores, whose asymmetries trace infall and…
Herschel observations of EXtra-Ordinary Sources: The Terahertz spectrum of Orion KL seen at high spectral resolution
N. R. Crockett, E. A. Bergin, S. Wang +60
We present the first high spectral resolution observations of Orion KL in the frequency ranges 1573.4 - 1702.8 GHz (band 6b) and 1788.4 - 1906.8 GHz (band 7b) obtained using the HI…
Herschel observations of ortho- and para-oxidaniumyl (H2O+) in spiral arm clouds toward Sgr B2(M)
