Description
Observations of the circumstellar envelope IRC + 10216 made with the James Clerk Maxwell Telescope are presented. Maps with the 14 min FWHM beam have been made in the CO J=3-2, CS J=7-6 and HCN J=4-3 transitions. The radial CO distribution agrees in shape with the Kwan/Linke outflow model, but is lower in intensity by an overall factor of 0.54. The HCN intensity is nearly double that of CO, but drops off almost twice as rapidly with distance from the source centre. Single spectra at the source centre are also presented for the isotopes 13CO, H13CN, C34S and for the lower excitation J=3-2 line of HCN and its isotope H13CN (with 23 min FWHM beam)
