The past, present and future of observations of externally irradiated disks

Planet formation environments collaboration, Megan Allen, Rossella Anania +51

Recent years have seen a surge of interest in the community studying the effect of ultraviolet radiation environment, predominantly set by OB stars, on protoplanetary disc evolutio…

PDRs4All XIII. Empirical prescriptions for the interpretation of JWST imaging observations of star-forming regions

Ryan Chown, Yoko Okada, Els Peeters +17

(Abridged) JWST continues to deliver incredibly detailed infrared (IR) images of star forming regions in the Milky Way and beyond. IR emission from star-forming regions is very spe…

On the origin of infrared bands attributed to tryptophan in Spitzer observations of IC 348

Aditya Dhariwal, Thomas H. Speak, Linshan Zeng +12

Infrared emission features toward interstellar gas of the IC 348 star cluster in Perseus have been recently proposed to originate from the amino acid tryptophan. The assignment was…

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…

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 III: JWST's NIR spectroscopic view of the Orion Bar

Els Peeters, Emilie Habart, Olivier Berne +135

(Abridged) We investigate the impact of radiative feedback from massive stars on their natal cloud and focus on the transition from the HII region to the atomic PDR (crossing the i…
