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 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…
Mid-infrared extinction curve for protostellar envelopes from JWST-detected embedded jet emission: the case of TMC1A
K. D. Assani, Z. -Y. Li, J. P. Ramsey +15
Context: Dust grains are key components of the interstellar medium and play a central role in star formation, acting as catalysts for chemical reactions and as building blocks of p…
The ALMA-PILS survey: Complex nitriles towards IRAS 16293--2422
H. Calcutt, J. K. Jørgensen, H. S. P. Müller +8
Complex organic molecules are readily detected in the inner regions of the gaseous envelopes of forming protostars. In particular, molecules that contain nitrogen are interesting d…
Laboratory Characterization and Astrophysical Detection of Vibrationally Excited States of Vinyl Cyanide in Orion-KL
A. López, B. Tercero, Z. Kisiel +11
New laboratory data of CHCHCN (vinyl cyanide) in its ground and vibrationally excited states at the microwave to THz domain allow searching for these excited state transitions…
The ALMA-PILS survey: 3D modeling of the envelope, disks and dust filament of IRAS 16293-2422
S. K. Jacobsen, J. K. Jørgensen, M. H. D. van der Wiel +8
Context. The Class 0 protostellar binary IRAS 16293-2422 is an interesting target for (sub)millimeter observations due to, both, the rich chemistry toward the two main components o…
