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…
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…
Investigating Protostellar Accretion-Driven Outflows Across the Mass Spectrum: JWST NIRSpec IFU 3-5~m Spectral Mapping of Five Young Protostars
Samuel Federman, S. Thomas Megeath, Adam E. Rubinstein +35
Investigating Protostellar Accretion is a Cycle 1 JWST program using the NIRSpec+MIRI integral field units to obtain 2.9--28 m spectral cubes of five young protostars with lumin…
CORINOS I: JWST/MIRI Spectroscopy and Imaging of a Class 0 protostar IRAS 15398-3359
Yao-Lun Yang, Joel D. Green, Klaus M. Pontoppidan +13
The origin of complex organic molecules (COMs) in young Class 0 protostars has been one of the major questions in astrochemistry and star formation. While COMs are thought to form…
Tracking the ice mantle history in the Solar-type Protostars of NGC 1333 IRAS 4
Marta De Simone, Cecilia Ceccarelli, Claudio Codella +13
To understand the origin of the diversity observed in exoplanetary systems, it is crucial to characterize the early stages of their formation, represented by Solar-type protostars.…
The chemical nature of Orion protostars: Are ORANGES different from PEACHES? ORANGES II
M. Bouvier, C. Ceccarelli, A. López-Sepulcre +3
Understanding the chemical past of our Sun and how life appeared on Earth is no mean feat. The best strategy we can adopt is to study newborn stars located in an environment simila…
ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): I. Detection of New Hot Corinos with ACA
Shih-Ying Hsu, Sheng-Yuan Liu, Tie Liu +29
We report the detection of four new hot corino sources, G211.47-19.27S, G208.68-19.20N1, G210.49-19.79W and G192.12-11.10 from a survey study of Planck Galactic Cold Clumps in the…
Constraining the Infalling Envelope Models of Embedded Protostars: BHR 71 and its Hot Corino
Y. -L. Yang, N. J. Evans, A. Smith +7
The collapse of the protostellar envelope results in the growth of the protostar and the development of a protoplanetary disk, playing a critical role during the early stages of st…
Diagnosing 0.1-10 au scale morphology of the FU\,Ori disk using ALMA and VLTI/GRAVITY
Hauyu Baobab Liu, Antoine Mérand, Joel D. Green +11
We report new Atacama Large Millimeter/submillimeter Array Band 3 (86-100 GHz; 80 mas angular resolution) and Band 4 (146-160 GHz; 50 mas angular resolution) observatio…
Variability in the Assembly of Protostellar Systems
Joel D. Green, Yao-Lun Yang, Tom Megeath +17
Understanding the collapse of clouds and the formation of protoplanetary disks is essential to understanding the formation of stars and planets. Infall and accretion, the mass-aggr…
The Herschel-PACS legacy of low-mass protostars: Properties of warm and hot gas and its origin in far-UV illuminated shocks
Agata Karska, Michael J. Kaufman, Lars E. Kristensen +11
Recent observations from Herschel allow the identification of important mechanisms responsible for the heating of gas surrounding low-mass protostars and its subsequent cooling in…
The Class 0 Protostar BHR71: Herschel Observations and Dust Continuum Models
Yao-Lun Yang, Neal J. Evans, Joel D. Green +2
We use Herschel spectrophotometry of BHR71, an embedded Class 0 protostar, to provide new constraints on its physical properties. We detect 645 (non-unique) spectral lines amongst…
The Mid-Infrared Evolution of the FU Orionis Disk
Joel D. Green, Olivia C. Jones, Luke D. Keller +6
We present new SOFIA-FORCAST observations obtained in Feburary 2016 of the archetypal outbursting low mass young stellar object FU Orionis, and compare the continuum, solid state,…
