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…

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…

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…

HDO ice detected toward an isolated low-mass protostar with JWST

Katerina Slavicinska, Łukasz Tychoniec, María Gabriela Navarro +15

Water is detected in environments representing every stage of star and solar system formation, but its chemical evolution throughout these stages remains poorly constrained. Deuter…

JWST observations of segregated CO and CO ices in protostellar envelopes

N. G. C. Brunken, A. C. A. Boogert, E. F. van Dishoeck +13

The evolution of interstellar ices can be studied with thermal tracers such as the vibrational modes of CO ice that show great diversity depending on their local chemical and t…

JWST-IPA: Chemical Inventory and Spatial Mapping of Ices in the Protostar HOPS370 -- Evidence for an Opacity Hole and Thermal Processing of Ices

Himanshu Tyagi, Manoj P., Mayank Narang +35

The composition of protoplanetary disks, and hence the initial conditions of planet formation, may be strongly influenced by the infall and thermal processing of material during th…

JWST detections of amorphous and crystalline HDO ice toward massive protostars

Katerina Slavicinska, Ewine F. van Dishoeck, Łukasz Tychoniec +19

This work aims to utilize the increased sensitivity and resolution of the JWST to quantify the HDO/HO ratio in ices toward young stellar objects (YSOs) and to determine if th…

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…

JWST Observations of Young protoStars (JOYS+): Detection of icy complex organic molecules and ions. I. CH, SO, HCOO, OCN, HCO, HCOOH, CHCHOH, CHCHO, CHOCHO, CHCOOH

W. R. M. Rocha, E. F. van Dishoeck, M. E. Ressler +23

Complex organic molecules (COMs) detected in the gas phase are thought to be mostly formed on icy grains, but no unambiguous detection of icy COMs larger than CH3OH has been report…

IPA: Class 0 Protostars Viewed in CO Emission Using JWST

Adam E. Rubinstein, Neal J. Evans, Himanshu Tyagi +24

We investigate the bright CO fundamental emission in the central regions of five protostars in their primary mass assembly phase using new observations from JWST's Near-Infrared Sp…

Discovery of a collimated jet from the low luminosity protostar IRAS 162532429 in a quiescent accretion phase with the JWST

Mayank Narang, Manoj P., Himanshu Tyagi +36

Investigating Protostellar Accretion (IPA) is a JWST Cycle~1 GO program that uses NIRSpec IFU and MIRI MRS to obtain 2.9--28~m spectral cubes of young, deeply embedded protostar…
