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…
Lyman-alpha Scattering Models Trace Accretion and Outflow Kinematics in T Tauri Systems
Nicole Arulanantham, Max Gronke, Eleonora Fiorellino +18
T Tauri stars produce broad Lyman-alpha emission lines that contribute 88% of the total UV flux incident on the inner circumstellar disks. Lyman-alpha photons are generated a…
A likely flyby of binary protostar Z CMa caught in action
Ruobing Dong, Hauyu Baobab Liu, Nicolas Cuello +16
Close encounters between young stellar objects in star forming clusters are expected to dramatically perturb circumstellar disks. Such events are witnessed in numerical simulations…
High-resolution spectroscopic monitoring observations of FU Orionis-type object, V960 Mon
Sunkyung Park, Jeong-Eun Lee, Tae-Soo Pyo +9
We present the results of high-resolution (R 30,000) optical and near-infrared spectroscopic monitoring observations of a FU Orionis-type object, V960 Mon, which underwent an…
