A breath of fresh air: Oxygen enhancement from silicate sublimation during early protostellar evolution
F. J. Ballieux, M. K. McClure, Ł. Tychoniec +5
Recently, an analog to the t = 0 moment of our Solar System's meteoritic record was identified for the first time around the Class I protostar HOPS-315. Crystalline silicates were…
Mapping of interstellar ices with JWST in protostellar envelopes: Spatial variations of CO, CO, CO, OCN and HO ice
N. G. C. Brunken, E. F. van Dishoeck, A. C. A. Boogert +16
The composition of planets and their atmospheres is largely determined by the formation environment of the planet. This environment is pre-determined during early stages when the p…
Impact of accretion variability on the CO emission of a disk around a very-low-mass star with JWST
C. Bergez-Casalou, B. Tabone, Y. Aoyama +14
Studying the structure of very-low-mass stars () protoplanetary disk is crucial to understand the formation of Earth-like planets. In this paper, we characteriz…
IPA: Morphology and Kinematics of Molecular Hydrogen Winds in Five Young Protostars across the Mass Spectrum Observed with JWST
Himanshu Tyagi, P. Manoj, Mayank Narang +29
Molecular winds may play a key role in governing angular momentum transport and accretion during the early evolution of protostars. We present the morphology and kinematic properti…
Probing outflow physics through CHCN and CHOH chemistry
L. Giani, D. Zaremba, M. De Simone +4
Chemical correlations between molecules provide powerful diagnostics to probe the physical conditions of protostellar outflows. In particular, the relationship between methanol (CH…
Jets and Outflows in Young Stellar Objects with the SKAO
Giovanni Sabatini, Gemma Busquet, Carlos Carrasco-González +48
Jets and outflows are ubiquitous phenomena associated with the formation of young stellar objects (YSOs). They play a crucial role in removing angular momentum from the accreting s…
JOYS: Launch and destruction of dust in protostellar jets. The case of BHR71-IRS1 with JWST MIRI
Łukasz Tychoniec, Logan Francis, Maria Gabriela Navarro +25
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: A JWST/MIRI survey of the evolution of H winds and jets from low-mass protostars
L. Francis, Ł. Tychoniec, E. F. van Dishoeck +20
Protostellar outflows display wide-angle winds and collimated jets, the magnetocentrifugal launching of which enables accretion onto the protostar. The majority of the outflow mass…
PENELLOPE: IX. Lithium, iron and barium elemental abundances in eight nearby young clusters
R. Carini, K. Biazzo, A. Frasca +19
We conducted a homogeneous chemical analysis of pre-main sequence stars with effective temperatures ranging from 3000 K to 5500 K in eight nearby star-forming regions…
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…
JOYS: JWST MIRI/MRS spectra of the inner 500 au region of the L1527 IRS bipolar outflow
R. Devaraj, E. F. van Dishoeck, T. P. Ray +12
This study characterized the physical and kinematic properties within the innermost 500 au region of the L1527 bipolar outflow, a class 0/I low-mass protostar using JWST MIRI/MRS s…
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…
