Mapping of interstellar ices with JWST in protostellar envelopes: Spatial variations of CO, CO, CO, OCN and HO ice

N. G. C. Brunken, E. F. van Dishoeck, A. C. A. Boogert +16

The composition of planets and their atmospheres is largely determined by the formation environment of the planet. This environment is pre-determined during early stages when the p…

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…

Quantifying the temperature-dependent yields of N and NH formation in vacuum-ultraviolet-irradiated NH ice

P. Samarth, G. Fedoseev, S. Ioppolo +3

Gas--grain astrochemical models predict that a substantial fraction of elemental nitrogen in dense cores and protoplanetary disks is locked in molecular nitrogen (N), in the ga…

In situ characterization of volatile and refractory hydrocarbons produced by UV photolysis of interstellar CH ice

P. Samarth, G. Fedoseev, M. Bulak +5

Acetylene (CH) is commonly observed in star-forming regions, young stellar objects, and the Solar System. Laboratory and theoretical studies have linked this simplest alkyn…

HO emission as tracer of pebble drift: insights from coupling transport and thermochemical models

Marissa Vlasblom, Andrew D. Sellek, Ewine F. van Dishoeck

(Abridged) The composition of the inner regions of protoplanetary disks is known to change with time due to the delivery of icy grains. Cold HO emission seen with JWST-MIRI is…

Cosmic Noon Galaxies in the Hubble Ultra Deep Field with MIRI Wide-Field Slitless Spectroscopy

S. Kendrew, G. Östlin, L. Colina +29

We present results from a survey of the Hubble Ultra-Deep Field using the Wide-Field Slitless Spectroscopic (WFSS) capability of the Mid-Infrared Instrument (MIRI) on JWST, demonst…
