PROJECT-J: The Shocking H2 Outflow from HH 46

The Astrophysical Journal
We analyze the H _2 emission observed in the HH 46 Class I system as part of PROtostellar JEts Cradle Tested with JWST (PROJECT-J), to investigate the origin and excitation of the warm molecular outflow. We used NIRSpec and MIRI spectral maps (1.6–27.9 μ

The Outflow of The Protostar in B335. I.

The Astronomical Journal
The isolated globule B335 contains a single, low-luminosity Class 0 protostar associated with a bipolar nebula and outflow system seen nearly perpendicular to its axis.

An Extremely Young Protostellar Core, MMS 1/OMC-3: Episodic Mass Ejection History Traced by the Micro SiO Jet

The Astrophysical Journal
We present ∼0.″2 (∼80 au) resolution observations of the CO(2–1) and SiO(5–4) lines made with the Atacama large millimeter/submillimeter array toward an extremely young intermediate-mass protostellar source ( t _dyn < 1000 yr), MMS 1 located in the Orion

Velocity asymmetries in young stellar object jets [PDF]

Context. It is well established that some YSO jets (e.g. RW Aur) display different propagation speeds between their blue and red shifted parts, a feature possibly associated with the central engine or the environment in which the jet propagates.\ud \ud Aims. To understand the origin of asymmetric YSO jet velocities, we investigate the efficiency of two

The Structure and Kinematics of Three Class 0 Protostellar Jets from JWST

The Astrophysical Journal
We present observations of jets within 2000 au of three deeply embedded protostars using 2.9–27 μ m observations with JWST. These observations show the morphologies and kinematics of the collimated jets from three protostars, the low-mass Class 0 ...

The Two Alternative Explosion Mechanisms of Core-Collapse Supernovae: 2024 Status Report

Universe
In comparing the two alternative explosion mechanisms of core-collapse supernovae (CCSNe), I examine recent three-dimensional (3D) hydrodynamical simulations of CCSNe in the frame of the delayed neutrino explosion mechanism (neutrino mechanism) and argue

Origin of the Shell Structure in the Primary Outflow from IRAS 15398−3359

The Astrophysical Journal
IRAS 15398−3359, a Class 0 protostar in the Lupus I star-forming region, is associated with three generations of outflows. The primary outflow, i.e., the most recent one, shows an internal structure named the “shell structure” in the near-infrared ...
