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…
Physical conditions in PDRs revealed by IGRINS ro-vibrational H2 observations
Aurélien Piluso, Vincent Maillard, Raphael Meshaka +10
We compare H2 high ro-vibrational observations of 5 PDRs (S140, IC63, Horsehead Nebula, NGC 2023 and Orion Bar) obtained with the IGRINS spectrograph to PDR models produced with th…
Impact of accretion variability on the CO emission of a disk around a very-low-mass star with JWST
C. Bergez-Casalou, B. Tabone, Y. Aoyama +14
Studying the structure of very-low-mass stars () protoplanetary disk is crucial to understand the formation of Earth-like planets. In this paper, we characteriz…
PDRs4All XXII. Near-Infrared continuum in the Orion Bar
Takashi Onaka, Emmanuel Dartois, Els Peeters +13
Conspicuous excess emission is present in the near-infrared (NIR) region in various objects, including reflection nebulae, planetary nebulae, and nearby galaxies. However, the spat…
Searching for the elusive CH2+ with the James Webb Space Telescope. Another carbocation to constrain astrochemical networks
M. Zannese, L. H. Coudert, E. Dartois +14
Carbocations are key species in interstellar chemistry, providing entry points for building larger hydrocarbons. CH+, and more recently, CH3+, have been detected. Other carbocation…
Chemistry and IR emission of acetylene in planet-forming regions of T Tauri disks. Impact of elemental abundances and dust properties
Pacôme Estève, Benoît Tabone, Emilie Habart +5
(Abridged) We aim to explore the parameters that influence the mid-infrared emission of CH and HO, and if the spread observed in / is tr…
