Discovery of a Compact Hub-Filament System in G286.21+0.17 with JWST and ALMA: Insights into Protocluster Formation and Competitive Accretion

Abstract We present a multi-wavelength study of the massive protocluster G286.21+0.17 (G286) using JWST near-infrared (NIR) imaging and ALMA H13CO+(1–0) observations. The JWST images uncover a compact (∼0.5 pc) hub-filament system (HFS), comprising a dense central hub connected b...
