The radiation from stars and active galactic nuclei (AGNs) creates photodissociation regions
(PDRs) and X-ray-dominated regions (XDRs), where the chemistry or heating is dominated …

Planets form in disks of gas and dust around young stars. The disk molecular reservoirs and
their chemical evolution affect all aspects of planet formation, from the coagulation of dust …

Carbon is an essential element for life but how much can be delivered to young planets is
still an open question. The chemical characterization of planet-forming disks is a crucial step …

Water is a fundamental molecule in the star and planet formation process, essential for
catalysing the growth of solid material and the formation of planetesimals within disks …

Abstract We present JWST-MIRI Medium Resolution Spectrometer (MRS) spectra of the
protoplanetary disk around the low-mass T Tauri star GW Lup from the MIRI mid-INfrared …

Molecular line observations are powerful tracers of the physical and chemical conditions
across the different evolutionary stages of star, disk, and planet formation. The high angular …

Sulfur-bearing molecules play an important role in prebiotic chemistry and planet
habitability. They are also proposed probes of chemical ages, elemental C/O ratio, and grain …

Context. The Mid-InfraRed Instrument (MIRI) Medium Resolution Spectrometer (MRS) on
board the James Webb Space Telescope (JWST) allows us to probe the inner regions of …

Context. Complex organic molecules (COMs) are ubiquitously detected in the gas phase
and thought to be mostly formed on icy grains. Nevertheless, there have not been any …

Context. Understanding the earliest stages of star formation, and setting it in the context of
the general cycle of matter in the interstellar medium, is a central aspect of research with the …
