JWST observations of photodissociation regions III. Dust modelling at the illuminated edge of the Horsehead PDR

M. Elyajouri, A. Abergel, N. Ysard +19

Carbonaceous nano-grains are a significant component of interstellar dust and dominate the mid-infrared emission of photodissociation regions (PDRs). We study the evolution of nano…

JWST observations of photodissociation regions: II. Warm molecular Hydrogen spectroscopy in the Horsehead nebula

M. Zannese, P. Guillard, A. Abergel +16

H2 is the most abundant molecule in the interstellar medium and is a useful tool to study photodissociation regions, where radiative feedback from massive stars on molecular clouds…

PDRs4All XIX. The 6 to 9 m region as a probe of PAH charge and size in the Orion Bar

Baria Khan, Samuel A. Daza Rodriguez, Els Peeters +24

Infrared emission from polycyclic aromatic hydrocarbons (PAHs) play a major role in determining the charge balance of their host environments that include photo-dissociation region…

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…

PDRs4All XI. Detection of infrared CH and CH rovibrational emission in the Orion Bar and disk d203-506: evidence of chemical pumping

Marion Zannese, Benoît Tabone, Emilie Habart +20

The methylidyne cation (CH) and the methyl cation (CH) are building blocks of organic molecules, yet their coupled formation and excitation mechanisms remain mainly unpro…
