Left: disk of WRAY 15-1880 as observed by ALMA in the 870 μm continuum. In all panels, the red square marks the position of the star; the open yellow circle is the expected position of the candidate planet observed with SPHERE at the epoch of the observations, assuming a circular Keplerian motion on the disk plane. The dashed red ellipse shows the position of the disk peak. Middle: geometric model for the dust distribution. Right: residuals between observation and model. The positions of the vortex and of the candidate companion are also marked. We note that the color scale (shown at bottom of each panel) was multiplied by 8 in this last image to show faint details.
