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…
UV-irradiated outflows from low-mass protostars in Ophiuchus with JWST/MIRI
I. M. Skretas, A. Karska, L. Francis +7
The main accretion phase of protostars is characterized by the ejection of material in the form of jets/outflows. External UV irradiation can potentially have a significant impact…
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…
JOYS: The [D/H] abundance derived from protostellar outflows across the Galactic disk measured with JWST
L. Francis, E. F. van Dishoeck, A. Caratti o Garatti +8
The total deuterium abundance [D/H] in the universe is set by just two processes: the creation of deuterium in Big Bang Nucleosynthesis at an abundance of [D/H]$=2.58\pm0.13\times1…
JOYS+: link between ice and gas of complex organic molecules. Comparing JWST and ALMA data of two low-mass protostars
Y. Chen, W. R. M. Rocha, E. F. van Dishoeck +16
A rich inventory of complex organic molecules (COMs) has been observed in high abundances in the gas phase toward Class 0 protostars. These molecules are suggested to be formed in…
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…
