Results from the parametric 2D modeling of HZ10 using PYAUTOGALAXY, in panels of 3′′ × 3′′. While the left panels contain the observed emission (colormap and black-solid contours), the middle and right panels show the best model using 2D Sérsic profiles (see Table 2 for more details) and the residuals after subtracting the maximum likelihood model, respectively. From top to bottom, panels contain the rest-frame 77 μm ALMA continuum (top row), 158 μm ALMA continuum (middle row), and [CII] 158 μm line emission (top row). The beam sizes of the data are represented by ellipses at the bottom-left of middle panels. For all the subplots, the contour are the [0 (dashed), 4σ, 5σ, and 6σ] levels. The figure confirms the binary nature of HZ10, which can be decomposed in HZ10-C (at the center), HZ10-W (to the left), and the bridge between the two main components (with at least a 5σ significance on the residual 158 μm continuum map). The latter seems to reflect the extended dusty component connecting HZ10-C and HZ10-W.
