Fig. 2


Binary α Cen at 100 μm (left: green) and 160 μm (right: red) at high contrast. Scales are in Jy/pxl, where square pixels are 1′′ on a side at 100 μm and 2′′ on a side at 160 μm. The field of view is 175 × 35. The image of α Cen is extended in the direction of the companion and, at 100 μm, the pair is quasi-resolved, having a separation of 57 along position angle 254°. The white arrows of length 80 AU correspond approximately to the stable circumbinary regime around α Cen AB. These point to parts of coherent structures that are also are seen at all FIR/submm wavelengths.
