Accretion onto the Embedded Protostar L1527 IRS: Insights from JWST NIRSpec and MIRI Observations
W. Blake Drechsler, John J. Tobin, Patrick D. Sheehan +12
Accretion is the primary driver of protostellar evolution, regulating mass assembly and shaping the physical and chemical environments of young stellar objects. Quantifying accreti…
JWST Observations of Young protoStars (JOYS): overview of program and early results
E. F. van Dishoeck, Å. 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…
Mid-infrared extinction curve for protostellar envelopes from JWST-detected embedded jet emission: the case of TMC1A
K. D. Assani, Z. -Y. Li, J. P. Ramsey +15
Context: Dust grains are key components of the interstellar medium and play a central role in star formation, acting as catalysts for chemical reactions and as building blocks of p…
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…
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…
