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…
JWST/MIRI Detection of Molecular H Winds from an Edge-on Class II Source HV Tau C
Vinod Chandra Pathak, P. Manoj, Himanshu Tyagi +14
The evolution of protoplanetary disks is regulated by accretion onto the central star and mass loss through jets and winds. While atomic and ionized outflows are commonly observed,…
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…
The Structure and Kinematics of Three Class 0 Protostellar Jets from JWST
Samuel A. Federman, S. Thomas Megeath, Alessio Caratti o Garatti +20
We present observations of jets within 2000 au of three deeply embedded protostars using 2.9-27 micron observations with JWST. These observations show the morphologies and kinemati…
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…
Improving Accretion Diagnostics for Young Stellar Objects with Mid-infrared Hydrogen lines from JWST/MIRI
B Shridharan, P Manoj, Vinod Chandra Pathak +10
We present a comprehensive study of mid-infrared neutral hydrogen (H~\textsc{i}) emission lines in 79 nearby (d 200 ) young stars using JWST/MIRI. We aim to identify mid-in…
Why are (almost) all the protostellar outflows aligned in Serpens Main?
Joel D. Green, Klaus M. Pontoppidan, Megan Reiter +4
We present deep 1.4-4.8 um JWST-NIRCam imaging of the Serpens Main star-forming region and identify 20 candidate protostellar outflows, most with bipolar structure and identified d…
Host star properties of hot, warm and cold Jupiters in the solar neighborhood from \textit{Gaia} DR3: clues to formation pathways
Bihan Banerjee, Mayank Narang, P. Manoj +5
Giant planets exhibit diverse orbital properties, hinting at their distinct formation and dynamic histories. In this paper, using DR3, we investigate if and how the…
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…
Chandra X-ray Analysis of Herbig Ae/Be Stars
Hema Anilkumar, Blesson Mathew, V. Jithesh +4
Herbig Ae/Be (HAeBe) stars are intermediate-mass pre-main sequence stars, characterized by infrared excess and emission lines. They are observed to emit X-rays, whose origin is a m…
UVIT/AstroSat observation of TW Hya
Prasanta K. Nayak, Mayank Narang, P. Manoj +7
The paper demonstrates the spectroscopic and photometric capabilities of the Ultra-Violet Imaging Telescope (UVIT) to study T-Tauri stars (TTSs). We present the first UVIT/Far-UV (…
Simultaneous FUV and NUV observations of T Tauri stars with UVIT/AstroSat: probing accretion process in young stars
Prasanta K. Nayak, Mayank Narang, P. Manoj +4
We present results from simultaneous FUV and NUV observations of T-Tauri stars (TTSs) in the Taurus molecular cloud with UVIT/AstroSat. This is the very first UVIT study of TTSs. F…
A uGMRT search for radio emission from planets around evolved stars
Mayank Narang, P. Manoj, Ishwara Chandra +8
In this work, we present the results from a study using the Giant Meterwave Radio Telescope (GMRT) to search for radio {emission} from planets around three evolved stars namely …
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…
