Constraining the Stellar Masses and Origin of the Protostellar VLA 1623 System

Sarah I Sadavoy, Patrick Sheehan, John J. Tobin +6

We present ALMA Band 7 molecular line observations of the protostars within the VLA 1623 system. We map CO (3 - 2) in the circumbinary disk around VLA 1623A and the outflow…

FAUST XV. A disk wind mapped by CHOH and SiO in the inner 300 au of the NGC 1333 IRAS 4A2 protostar

M. De Simone, L. Podio, L. Chahine +23

Context. Understanding the connection between outflows, winds, accretion and disks in the inner protostellar regions is crucial for comprehending star and planet formation process.…

The Asymmetric Bipolar Fe II Jet and H2 Outflow of TMC1A Resolved with JWST's NIRSpec IFU

Korash Assani, Daniel Harsono, Jon Ramsey +10

(abridged) Protostellar outflows exhibit large variations in their structure depending on the observed gas emission. This study analyzes the atomic jet and molecular outflow in 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…

Episodicity in accretion-ejection processes associated with IRAS 15398-3359

E. Guzmán Ccolque, M. Fernández López, M. M. Vazzano +3

The protostar IRAS 15398-3359 is associated with a bipolar molecular outflow ejected in an nearly northeast-southwest (NE-SW) direction which has been extensively studied. It has b…

The Kinematic and Dynamic Properties of HBC 494's Wide-Angle Outflows

Austen Fourkas, Dary Ruiz-Rodriguez, Lee G. Mundy +1

We present Atacama Large Millimeter/sub-millimeter Array (ALMA) Cycle-5 observations of HBC 494, as well as calculations of the kinematic and dynamic variables which represent the…
