Image of IRC+10216 at 43.3 GHz (6.9 mm). The brightness distribution is shown in grey scale. Contours give −5, 5, 10, 30, 50, 70, 90, and 99 percent of the peak brightness, which is 4.1 mJy beam^-1. The rms noise level in the image, 92   μJy, corresponds to 2.2% of that peak value. The 41 mas FWHM symmetric restoring beam is represented in the lower left corner. The 83 mas diameter dashed circle gives the size of IRC+10216’s radio photosphere derived by fitting a uniform disk brightness distribution to our VLA data. The dotted circle of diameter 29 mas represents the diameter of the star’s photosphere derived from the luminosity we determine and assuming an effective temperature of 2850 K. Note that the major axes of Mars’ and Jupiter’s orbits (3.0 and 10.4 AU, respectively) would have angular diameters of 23 and 80 mas at a distance of 130 pc.
