Fig. 7
Map of the spectral index in HD 135344B, calculated between the Band 4 and the Band 7 data. A clear azimuthal variation in the value of α can be seen, consistent with the presence of large grains trapped inside a vortex. The typical uncertainty is ± 0.3. White contours show the Band 4 intensity profile at 0.08′′ resolution to highlight the location of the crescent. The ellipse shows the beam size of the Band 4 and Band 7 maps.
