Detection of the Polycyclic Aromatic Hydrocarbon Phenalene (CH) in the Very Low Luminosity Object (VeLLO) MC27/L1521F
Gabi Wenzel, Thomas H. Speak, Ci Xue +12
To date, 14 polycyclic aromatic hydrocarbons (PAHs) ranging in size from two to seven (including five- and six-membered) carbon rings have been detected in the starless dense core…
Modeling the Effect of C/O Ratio on Complex Carbon Chemistry in Cold Molecular Clouds
Alex N. Byrne, Christopher N. Shingledecker, Edwin A. Bergin +5
Elemental abundances, which are often depleted with respect to the solar values, are important input parameters for kinetic models of interstellar chemistry. In particular, the amo…
The Molecular Inventory of TMC-1 with GOTHAM Observations
Ci Xue, Alex N. Byrne, Larry Morgan +14
Spectral line surveys of the Taurus Molecular Cloud-1 (TMC-1) have led to the detection of more than 100 new molecular species, making it the most prolific source of interstellar m…
Grand Design Spiral Arms in the Compact, Embedded Protoplanetary Disk of Haro 6-13
Jane Huang, Masataka Aizawa, Jaehan Bae +6
Millimeter continuum spiral arms have so far only been detected in a handful of protoplanetary disks, and thus we have a limited understanding of the circumstances in which they ca…
Solar C/O ratio in planet-forming gas at 1 au in a highly irradiated disk
Ilane Schroetter, Olivier Berné, Emeric Bron +18
The chemical composition of exoplanets is thought to be influenced by the composition of the disks in which they form. JWST observations have unveiled a variety of species in numer…
Discovery of the 7-ring PAH Cyanocoronene (CHCN) in GOTHAM Observations of TMC-1
Gabi Wenzel, Siyuan Gong, Ci Xue +18
We present the synthesis and laboratory rotational spectroscopy of the 7-ring polycyclic aromatic hydrocarbon (PAH) cyanocoronene (CHCN) using a laser-ablation assist…
Detections of interstellar 2-cyanopyrene and 4-cyanopyrene in TMC-1
Gabi Wenzel, Thomas H. Speak, P. Bryan Changala +19
Polycyclic aromatic hydrocarbons (PAHs) are among the most ubiquitous compounds in the universe, accounting for up to ~25% of all interstellar carbon. Since most unsubstituted PAHs…
Discovery of interstellar 1-cyanopyrene: a four-ring polycyclic aromatic hydrocarbon in TMC-1
Gabi Wenzel, Ilsa R. Cooke, P. Bryan Changala +22
Polycyclic aromatic hydrocarbons (PAHs) are expected to be the most abundant class of organic molecules in space. Their interstellar lifecycle is not well understood, and progress…
Chemical abundance gradients of organic molecules within a protostellar disk
Levi G. Walls, Merel L. R. van 't Hoff, Edwin A. Bergin
Observations of low-mass protostellar systems show evidence of rich complex organic chemistry. Their low luminosity, however, makes determining abundance distributions of complex o…
Constraints on the gas-phase C/O ratio of DR Tau's outer disk from CS, SO, and CH observations
Jane Huang, Edwin A. Bergin, Romane Le Gal +4
Millimeter wavelength observations of Class II protoplanetary disks often display strong emission from hydrocarbons and high CS/SO values, providing evidence that the gas-phase C/O…
PDRs4All II: JWST's NIR and MIR imaging view of the Orion Nebula
Emilie Habart, Els Peeters, Olivier Berné +139
The JWST has captured the most detailed and sharpest infrared images ever taken of the inner region of the Orion Nebula, the nearest massive star formation region, and a prototypic…
Velocity-resolved [CII] emission and [CII]/FIR Mapping along Orion with Herschel
J. R. Goicoechea, D. Teyssier, M. Etxaluze +22
We present the first 7.5'x11.5' velocity-resolved map of the [CII]158um line toward the Orion molecular cloud-1 (OMC-1) taken with the Herschel/HIFI instrument. In combination with…
Herschel/HIFI observations of [CII] and [13CII] in PDRs
V. Ossenkopf, M. Röllig, D. A. Neufeld +5
Recently, we introduced detailed isotopic chemistry into the KOSMA-tau model for photon-dominated regions (PDRs) to give theoretical predictions for the abundance of the carbon iso…
Beyond the pseudo-time-dependent approach: chemical models of dense core precursors
G. E. Hassel, E. Herbst, E. A. Bergin
Context: Chemical models of dense cloud cores often utilize the so-called pseudo-time-dependent approximation, in which the physical conditions are held fixed and uniform as the ch…
