JOYS+ analyses of OCN, NO, NO, and complex cyanides in ices -- Thermal processing results in modest enhancement of OCN ice
P. Nazari, N. Brunken, Y. Chen +12
Nitrogen-bearing molecules are more difficult to observe than oxygen-bearing ones, mainly due to the lower abundance of nitrogen in the interstellar medium. Therefore, the formatio…
JOYS: Linking the molecular ice and gas-phase composition towards the high-mass hot core IRAS 18089-1732
C. Gieser, W. R. M. Rocha, Y. Chen +11
Context. The formation and destruction of molecules in the interstellar medium is a complex interplay between gas-phase reactions as well as processes on grain surfaces and within…
Unlocking accretion rate diagnostics for high-mass protostars using JWST/MIRI HI lines
S. D. Reyes-Reyes, H. Beuther, E. F. van Dishoeck +14
While many aspects of high-mass star formation have been investigated, the accretion onto the central protostars is one of the most fundamental but less explored physical propertie…
Protostars at Subsolar Metallicity: First Detection of Large Solid-state Complex Organic Molecules in the Large Magellanic Cloud
Marta Sewiło, Will R. M. Rocha, Martijn van Gelder +11
We present the results of James Webb Space Telescope observations of the protostar ST6 in the Large Magellanic Cloud (LMC) with the Medium Resolution Spectrograph of the Mid-Infrar…
Ice inventory towards the protostar Ced 110 IRS4 observed with the James Webb Space Telescope. Results from the ERS Ice Age program
W. R. M. Rocha, M. K. McClure, J. A. Sturm +37
This work focuses on the ice features toward the binary protostellar system Ced 110 IRS 4A and 4B, and observed with JWST as part of the Early Release Science Ice Age collaboration…
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…
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…
JWST ice band profiles reveal mixed ice compositions in the HH 48 NE disk
Jennifer B. Bergner, J. A. Sturm, Elettra L. Piacentino +19
Planet formation is strongly influenced by the composition and distribution of volatiles within protoplanetary disks. With JWST, it is now possible to obtain direct observational c…
A JWST/MIRI analysis of the ice distribution and PAH emission in the protoplanetary disk HH 48 NE
J. A. Sturm, M. K. McClure, D. Harsono +18
Ice-coated dust grains provide the main reservoir of volatiles that play an important role in planet formation processes and may become incorporated into planetary atmospheres. How…
The edge-on protoplanetary disk HH 48 NE II. Modeling ices and silicates
J. A. Sturm, M. K. McClure, J. B. Bergner +11
The abundance and distribution of ice in protoplanetary disks (PPD) is critical to understand the linkage between the composition of circumstellar matter and the composition of exo…
The edge-on protoplanetary disk HH 48 NE I. Modeling the geometry and stellar parameters
J. A. Sturm, M. K. McClure, C. J. Law +11
Context. Observations of edge-on disks are an important tool for constraining general protoplanetary disk properties that cannot be determined in any other way. However, most radia…
Multiwavelength Study of Dark Globule DC 314.8-5.1: Point Source Identification and Diffuse Emission Characterization
E. Kosmaczewski, L. Stawarz, C. C. Cheung +3
We present an analysis of multi-wavelength observations of the dark globule DC\,314.8--5.1, using data from the Gaia optical, 2MASS near-infrared, and WISE mid-infrared surveys, de…
Spectroscopic Diagnostics of the Mid-Infrared Features of the Dark Globule, DC 314.8-5.1, with the Spitzer Space Telescope
E. Kosmaczewski, Ł. Stawarz, W. R. M. Rocha +2
We present an analysis of the mid-infrared spectra, obtained from the Spitzer Space Telescope, of the dark globule, DC 314.8--5.1, which is at the onset of low-mass star formation.…
