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: Launching and destruction of dust in protostellar jets. The case of BHR71-IRS1 with JWST/MIRI

Łukasz Tychoniec, Logan Francis, Maria Gabriela Navarro +24

Protostellar winds can theoretically lift solids from the planet-forming disks, but direct evidence for launched dust has been scarce so far. Numerous atomic lines that are unique…

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…

Investigating the Nested Structure of the Outflow from the Low Luminosity Protostar IRAS 16253-2429 using JWST and ALMA

Mayank Narang, Himanshu Tyagi, Nagayoshi Ohashi +37

Understanding the earliest stage of star and planet formation requires detailed observations to address the connection and interplay between the accretion, outflow and disk evoluti…

IPA. Accretion rate of a low-mass Class 0 protostar, measured via mid-infrared fluorescent OH emission

Dan M. Watson, Mayank Narang, Caeley V. Pittman +41

The earliest stages of star formation are highlighted by complex interactions between accretion, outflow, and radiative processes, which shape the chemical and physical environment…

JWST Observations of Young protoStars (JOYS): overview of program and early results

E. F. van Dishoeck, Ł. Tychoniec, W. R. M. Rocha +34

The embedded phase is a crucial period in the development of a young star. Mid-IR observations, now possible with JWST with unprecedented sensitivity, spectral resolution and sharp…
