H2 emission in the Orion Bar, NGC7023 and the Horsehead Nebula observed with the James Webb Space Telescope

M. Zannese, A. Sidhu, A. Guerras +25

Molecular hydrogen (H2), the most abundant molecule in the interstellar medium, is a handy tool to study Photodissociation Regions. The JWST, with its high spatial resolution, sens…

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…

PDRs4All IV. An embarrassment of riches: Aromatic infrared bands in the Orion Bar

Ryan Chown, Ameek Sidhu, Els Peeters +136

(Abridged) Mid-infrared observations of photodissociation regions (PDRs) are dominated by strong emission features called aromatic infrared bands (AIBs). The most prominent AIBs ar…

Astrochemical models of interstellar ices: History matters

A. Clément, A. Taillard, V. Wakelam +6

Ice is ubiquitous in the interstellar medium. We model the formation of the main constituents of interstellar ices, including H2O, CO2 , CO, and CH3 OH. We strive to understand wha…

The edge-on protoplanetary disk HH 48 NE II. Modeling ices and silicates

J. A. Sturm, M. K. McClure, J. B. Bergner +11

The abundance and distribution of ice in protoplanetary disks (PPD) is critical to understand the linkage between the composition of circumstellar matter and the composition of exo…

The edge-on protoplanetary disk HH 48 NE I. Modeling the geometry and stellar parameters

J. A. Sturm, M. K. McClure, C. J. Law +11

Context. Observations of edge-on disks are an important tool for constraining general protoplanetary disk properties that cannot be determined in any other way. However, most radia…
