PDRs4All. XII. FUV-driven formation of hydrocarbon radicals and their relation with PAHs
J. R. Goicoechea, J. Pety, S. Cuadrado +25
We present subarcsecond-resolution ALMA mosaics of the Orion Bar PDR in [CI] 609um, C2H (4-3), and C18O (3-2) emission lines complemented by JWST images of H2 and aromatic infrared…
Tracking the Chemical Evolution of Hydrocarbons Through Carbon Grain Supply in Protoplanetary Disks
Eshan Raul, Felipe Alarcón, Edwin A. Bergin
The gas present in planet-forming disks typically exhibits strong emission features of abundant carbon and oxygen molecular carriers. In some instances, protoplanetary disks show a…
PDRs4All. X. ALMA and JWST detection of neutral carbon in the externally irradiated disk d203-506: Undepleted gas-phase carbon
Javier R. Goicoechea, J. Le Bourlot, J. H. Black +26
The gas-phase abundance of carbon, x_C = C/H, and its depletion factors are essential parameters for understanding the gas and solid compositions that are ultimately incorporated i…
Thermal Structure and Millimeter Emission of Protoplanetary Disk with embedded protoplanets from radiative transfer modeling
Felipe Alarcón, Edwin Bergin
The discovery of protoplanets and circumplanetary disks provides a unique opportunity to characterize planet formation through observations. Massive protoplanets shape the physical…
Extinction values towards embedded planets in protoplanetary disks estimated from hydrodynamic simulations
Felipe Alarcón, Edwin Bergin, Gabriele Cugno
The upcoming new coronographs with deeper contrast limits, together with planned and current high-contrast imaging campaigns will push the detectability limit of protoplanets. Thes…
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…
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…
OH as a probe of the warm water cycle in planet-forming disks
Marion Zannese, Benoît Tabone, Emilie Habart +52
Water is a key ingredient for the emergence of life as we know it. Yet, its destruction and reformation in space remains unprobed in warm gas. Here, we detect the hydroxyl radical…
Viscous heating as the dominant heat source inside the water snowline of V883 Ori
Felipe Alarcón, Simón Casassus, Wladimir lyra +2
FU Orionis-type objects(FUors) are embedded protostars that undergo episodes of high accretion, potentially indicating a widespread but poorly understood phase in the formation of…
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…
