Magnetic field measurements in a sample of Class I and flat-spectrum protostars observed with SPIRou
L. Drouglazet, E. Alecian, A. Sousa +27
Magnetic fields play a crucial role throughout stellar evolution, regulating angular momentum, channelling accretion, and launching jets and outflows. While the magnetic properties…
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…
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…
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…
JWST Observations of Young protoStars (JOYS). Overview of gaseous molecular emission and absorption in low-mass protostars
M. L. van Gelder, L. Francis, E. F. van Dishoeck +17
The MIRI-MRS instrument onboard JWST allows for probing the molecular gas composition at mid-IR wavelengths at unprecedented resolution and sensitivity. It is important to study th…
JWST Observations of Young protoStars (JOYS). HH 211: the textbook case of a protostellar jet and outflow
A. Caratti o Garatti, T. P. Ray, P. J. Kavanagh +22
We use the James Webb Space Telescope (JWST) and its Mid-Infrared Instrument (MIRI) (5-28 um), to study the embedded HH 211 flow. We map a 0.95'x0.22' region, covering the full ext…
JWST Observations of Young protoStars (JOYS): Linked accretion and ejection in a Class I protobinary system
Łukasz Tychoniec, Martijn L. van Gelder, Ewine F. van Dishoeck +19
Accretion and ejection sets the outcome of the star and planet formation process. The mid-infrared wavelength range offers key tracers of those processes that were difficult to det…
