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…

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…

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…

PDRs4All: A JWST Early Release Science Program on radiative feedback from massive stars

Olivier Berné, Émilie Habart, Els Peeters +134

Massive stars disrupt their natal molecular cloud material through radiative and mechanical feedback processes. These processes have profound effects on the evolution of interstell…

Extended Red Emission: Observational constraints for models

Adolf N. Witt, Thomas S. -Y. Lai

Extended Red Emission (ERE) is a widely observed optical emission process, present in a wide range of circumstellar and interstellar environments in the Milky Way galaxy as well as…

Are the Carriers of Diffuse Interstellar Bands and Extended Red Emission the same?

Thomas S. -Y. Lai, Adolf N. Witt, Carlos Alvarez +1

We report the first spectroscopic observations of a background star seen through the region between the ionization front and the dissociation front of the nebula IC 63. This photod…
