Panel a) IRAM PdBI continuum-subtracted map of the CO(1–0) narrow core emission in IRAS F10565+2448. Contours correspond to 50σ. The inset b) shows the first moment map obtained within v ∈ ( − 200, 200) km s^-1. Contours correspond to 3 km s^-1. The size of this inset is 10 × 13 arcsec. Panel c) uv plot for the narrow core, with visibilities binned in uv radius steps of 5 m, fitted with a power-law function model of the form ∝ r^-3 (red points).
