Connecting CO blobs detected by ALMA and JWST observations

ABSTRACT :
Protostellaroutflow/jet often exhibit knotty features, which serves as evidence for episodic accretion in stellar mass growth. Over time, these knot features in jets move, allowing for a precise measure of their kinematics, including their proper motions and inclinations. Specifically, in the case of B335, observations conducted by both ALMA and JWST at different times have revealed the presence of CO blobs. This study aims to analyze the CO blobs detected in these observations to determine if they represent the same ejection gas. Furthermore, this study will improve our understanding of the dynamics and mechanisms of the blob feature of jet in B335.
