ALMA 338 GHz Briggs-weighted (robust 0) continuum image of Betelgeuse. Gray contours are set to (− 3,3,10,100,300) × σ_rms where σ_rms = 85 μJy beam^-1 is the image rms noise. The numbers within the contours are the flux density values they represent in mJy. The largest contour is displayed in red for clarity at 54 mJy or 635σ_rms. The filled ellipse in the lower left corner is the full width at half maximum (FWHM) of the restoring beam and has dimensions 15 × 13 mas. The locations of the NE-peak and the east-extension are marked with “×” and “+”, respectively. The yellow circle is the size of the infrared H-band photosphere from Montargès et al. (2016).
