The panels represent the three highest angular resolution epochs of ALMA observations at 338 GHz. The black ellipse in the panels indicates the average size of the stellar disk at this frequency. The red solid contours and the blue dashed contours indicate the positive and negative 4, 5 and 6σ features with respect to the mean emission of the stellar disk. The size and orientation of the interferometric beam is indicated at the bottom left of each panel. DEC, declination; RA, right ascension.
