Gas phase Elemental abundances in Molecular cloudS (GEMS). X. Observational effects of turbulence on the chemistry of molecular clouds
L. Beitia-Antero, A. Fuente, D. Navarro-Almaida +12
(Abridged) We explore the chemistry of the most abundant C, O, S, and N bearing species in molecular clouds, in the context of the IRAM 30 m Large Programme Gas phase Elemental abu…
Detection of Dimethyl Ether in the Central Region of the MWC 480 Protoplanetary Disk
Yoshihide Yamato, Yuri Aikawa, Viviana V. Guzmán +9
Characterizing the chemistry of complex organic molecules (COMs) at the epoch of planet formation provides insights into the chemical evolution of the interstellar medium (ISM) and…
FAUST XVII: Super deuteration in the planet forming system IRS 63 where the streamer strikes the disk
L. Podio, C. Ceccarelli, C. Codella +55
Recent observations suggest that planets formation starts early, in protostellar disks of yrs, which are characterized by strong interactions with the environment, e.g.,…
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 VIII: Mid-IR emission line inventory of the Orion Bar
Dries Van De Putte, Raphael Meshaka, Boris Trahin +135
Mid-infrared emission features probe the properties of ionized gas, and hot or warm molecular gas. The Orion Bar is a frequently studied photodissociation region (PDR) containing l…
FAUST XIII. Dusty cavity and molecular shock driven by IRS7B in the Corona Australis cluster
G. Sabatini, L. Podio, C. Codella +54
The origin of the chemical diversity observed around low-mass protostars probably resides in the earliest history of these systems. We aim to investigate the impact of protostellar…
PDRs4All IX. Sulfur elemental abundance in the Orion Bar
Asunción Fuente, Evelyne Roueff, Franck Le Petit +31
One of the main problems in astrochemistry is determining the amount of sulfur in volatiles and refractories in the interstellar medium. The detection of the main sulfur reservoirs…
Anatomy of the Class I protostar L1489 IRS with NOEMA -- I. Disk, streamers, outflow(s) and bubbles at 3mm
M. Tanious, R. Le Gal, R. Neri +7
Over the past few years, chemical studies have revealed multiple structures in the vicinity of young stellar objects (YSOs). It has become evident that specific physical conditions…
Grain growth and its chemical impact in the first hydrostatic core phase
D. Navarro-Almaida, U. Lebreuilly, P. Hennebelle +8
The first hydrostatic core (FHSC) phase is a brief stage in the protostellar evolution that is difficult to detect. Our goal is to characterize the chemical evolution of gas and du…
A far-ultraviolet-driven photoevaporation flow observed in a protoplanetary disk
Olivier Berné, Emilie Habart, Els Peeters +143
Most low-mass stars form in stellar clusters that also contain massive stars, which are sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiati…
JWST-MIRI Spectroscopy of Warm Molecular Emission and Variability in the AS 209 Disk
Carlos E. Romero-Mirza, Karin I. Öberg, Andrea Banzatti +24
We present MIRI MRS observations of the large, multi-gapped protoplanetary disk around the T-Tauri star AS 209. The observations reveal hundreds of water vapor lines from 4.9 to 25…
Protonated acetylene in the z=0.89 molecular absorber toward PKS1830-211
S. Muller, R. Le Gal, E. Roueff +7
We report the first interstellar identification of protonated acetylene, C2H3+, a fundamental hydrocarbon, in the z=0.89 molecular absorber toward the gravitationally lensed quasar…
Formation of the Methyl Cation by Photochemistry in a Protoplanetary Disk
Olivier Berné, Marie-Aline Martin-Drumel, Ilane Schroetter +53
Forty years ago it was proposed that gas phase organic chemistry in the interstellar medium was initiated by the methyl cation CH3+, but hitherto it has not been observed outside t…
