JWST-IPA: Chemical Inventory and Spatial Mapping of Ices in the Protostar HOPS370 -- Evidence for an Opacity Hole and Thermal Processing of Ices
Himanshu Tyagi, Manoj P., Mayank Narang +35
The composition of protoplanetary disks, and hence the initial conditions of planet formation, may be strongly influenced by the infall and thermal processing of material during th…
JWST Observations of Young protoStars (JOYS). Overview of gaseous molecular emission and absorption in low-mass protostars
M. L. van Gelder, L. Francis, E. F. van Dishoeck +17
The MIRI-MRS instrument onboard JWST allows for probing the molecular gas composition at mid-IR wavelengths at unprecedented resolution and sensitivity. It is important to study th…
JOYS+ study of solid state C/C isotope ratios in protostellar envelopes: Observations of CO and CO ice with JWST
N. G. C. Brunken, E. F. van Dishoeck, K. Slavicinska +12
The carbon isotope ratio is a powerful tool for studying the evolution of stellar systems. Recent detections of CO isotopologues in disks and exoplanet atmospheres pointed towards…
Star Formation
Rajika Kuruwita, Łukasz Tychoniec, Christoph Federrath
In this chapter, we will cover how stars form from the stellar nurseries that are giant molecular clouds. We will first review the physical processes that compete to regulate star…
JWST detections of amorphous and crystalline HDO ice toward massive protostars
Katerina Slavicinska, Ewine F. van Dishoeck, Łukasz Tychoniec +19
This work aims to utilize the increased sensitivity and resolution of the JWST to quantify the HDO/HO ratio in ices toward young stellar objects (YSOs) and to determine if th…
JWST study of the DG Tau B disk wind candidate: I -- Overview and Nested H/CO outflows
Valentin Delabrosse, Catherine Dougados, Sylvie Cabrit +5
The origin and impact of outflows on proto-planetary disks and planet formation are key open questions. DG Tau B, a Class I protostar with a structured disk and a striking rotating…
JWST observations of CO ice: Tracing the chemical environment and thermal history of ices in protostellar envelopes
Nashanty G. C. Brunken, Will R. M. Rocha, Ewine F. van Dishoeck +38
The structure and composition of simple ices can be modified during stellar evolution by protostellar heating. Key to understanding the involved processes are thermal and chemical…
JWST Observations of Young protoStars (JOYS): Linked accretion and ejection in a Class I protobinary system
Łukasz Tychoniec, Martijn L. van Gelder, Ewine F. van Dishoeck +19
Accretion and ejection sets the outcome of the star and planet formation process. The mid-infrared wavelength range offers key tracers of those processes that were difficult to det…
JOYS: MIRI/MRS spectroscopy of gas-phase molecules from the high-mass star-forming region IRAS 23385+6053
L. Francis, M. L. van Gelder, E. F. van Dishoeck +16
Space-based mid-IR spectroscopy provides tracers of warm gas in star-forming regions that are inaccessible from the ground. Past mid-IR spectra of bright high-mass protostars in th…
