JWST composite image and ALMA SiO and CO images of the HH 211 outflow. (a) The JWST composite image: blue for F335M (several H\(_2\) lines and continuum nebulosity), green for F460M (4.69 μm H\(_2\) line, CO rotational-vibrational band head emission, and continuum nebulosity), and red for F470N (4.69 μm H\(_2\) line) filters. The cross marks the position of the protostar located at ICRS \(\alpha _{(2000)}=3^\textrm{h} 43^\textrm{m} 56^\textrm{s}_{^{.}} 808\) and \(\delta _{(2000)}=32^{\circ }00^{\prime }50^{\prime \prime }_{^{.}}1535\)11. (b) Zooms in to the inner region in the JWST image. (c) The ALMA SiO image (green) with the JWST image. (d) The ALMA CO image (green) with the JWST image. The CO map is obtained with \(v_\text {rel}\sim -30\) to \(-16\) km s−1 for the SE component and 19 to 32 km s−1 for the NW component to avoid any significant contamination of the shells, where \(v_\text {rel}\) is the radial velocity relative to the systemic velocity of \(\sim\) 9.2 km s−1. The insert shows the innermost part of the CO jet with the continuum map of the disk (gray image) reported before11. The resolutions are \(\sim\) 10 au for SiO and CO in panels c and d, and \(\sim\) 7.5 au for CO in the insert.
