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…
Length-scales and Dynamics of Carina's Western Wall
Turlough Downes, Patrick Hartigan, Andrea Isella
We present a variety of analyses of the turbulent dynamics of the boundary of a photo-dissociation region (PDR) in the Carina Nebula using high resolution ALMA observations. Using…
ALMA Datacubes and Continuum Maps of the Irradiated Western Wall in Carina
Patrick Hartigan, Maxwell Hummel, Andrea Isella +1
We present ALMA observations of the continuum and line emission of CO, CO, CO, and [C I] for a portion of the G287.38-0.62 (Car 1-E) region in the Carina star-…
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…
A JWST Preview: Adaptive-Optics Images of H, Br-, and K-continuum in Carina's Western Wall
Patrick Hartigan, Turlough Downes, Andrea Isella
We present the first wide-field near-infrared adaptive optics images of Carina's Western Wall (G287.38-0.62), one of the brightest and most well-defined irradiated interfaces known…
