Linking ice and gas in the Coronet cluster in Corona Australis
G. Perotti, J. K. Jørgensen, W. R. M. Rocha +7
During the journey from the cloud to the disc, the chemical composition of the protostellar envelope material can be either preserved or processed to varying degrees depending on t…
Protostellar Interferometric Line Survey of the Cygnus-X region (PILS-Cygnus) -- The role of the external environment in setting the chemistry of protostars
S. J. van der Walt, L. E. Kristensen, H. Calcutt +2
(Abridged) Molecular lines are commonly detected towards protostellar sources. However, to get a better understanding of the chemistry of these sources we need unbiased molecular s…
Shock excitation of H in the James Webb Space Telescope era
L. E. Kristensen, B. Godard, P. Guillard +2
(Abridged) H2 is the most abundant molecule in the Universe. Thanks to its widely spaced energy levels, it predominantly lights up in warm gas, T > 100 K, such as shocked regions,…
Episodic infall towards a compact disk in B335?
Per Bjerkeli, Jon P. Ramsey, Daniel Harsono +7
Previous observations of B335 have presented evidence of ongoing infall in various molecular lines, e.g., HCO, HCN, CO. There have been no confirmed observations of a rotationa…
JWST Peers into the Class I Protostar TMC1A: Atomic Jet and Spatially Resolved Dissociative Shock Region
Daniel Harsono, Per Bjerkeli, Jon Ramsey +6
Outflows and winds launched from young stars play a crucial role in the evolution of protostars and the early stages of planet formation. However, the specific details of the mecha…
Investigating the Impact of Metallicity on Star Formation in the Outer Galaxy. I. VLT/KMOS Survey of Young Stellar Objects in Canis Major
Dominika Itrich, Agata Karska, Marta Sewiło +9
The effects of metallicity on the evolution of protoplanetary disks may be studied in the outer Galaxy where the metallicity is lower than in the solar neighbourhood. We present th…
Far-infrared line emission from the outer Galaxy cluster Gy 3-7 with SOFIA/FIFI-LS: Physical conditions and UV fields
N. Le, A. Karska, M. Figueira +13
(abridged) Far-infrared (FIR) line emission provides key information about the gas cooling and heating due to shocks and UV radiation associated with the early stages of star forma…
Star-formation-rate estimates from water emission
K. M. Dutkowska, L. E. Kristensen
(Abridged) The star-formation rate (SFR) quantitatively describes the star-formation process in galaxies. Current ways to calibrate this rate do not usually employ observational me…
Simulation of CHOH ice UV photolysis under laboratory conditions
W. R. M. Rocha, P. Woitke, S. Pilling +5
Methanol is the most complex molecule securely identified in interstellar ices and is a key chemical species for understanding chemical complexity in astrophysical environments. Im…
An Ice Age JWST inventory of dense molecular cloud ices
M. K. McClure, W. R. M. Rocha, K. M. Pontoppidan +39
Icy grain mantles are the main reservoir of the volatile elements that link chemical processes in dark, interstellar clouds with the formation of planets and composition of their a…
