IRAS16547_ALMA_combined_insets3

ALMA composite image of a massive binary protostar IRAS 16547-4247. Different colors show the different distributions of dust particles (yellow), methyl cyanide (CH3CN, red), salt (NaCl, green), and hot water vapor (H2O, blue). The bottom insets are the close-up views of each component. Dust and methyl cyanide are distributed widely around the binary, whereas salt and water vapor concentrate in the disk around each protostar. In the wide-field image, the jets from one of the protostars, seen as several dots in the above image, are shown in light blue. Credit: ALMA (ESO/NAOJ/NRAO), Tanaka et al.
