Comparison of the disk radial profiles (upper panel: surface mass density, middle panel: temperature and lower panel: mass flux) for the disk at 4 Myr in the present paper (black line) and a 1 million-year-old disk evolved from an MMSN in BCP16 (red). We notice that the new treatment of the disk self-shadowing induces the presence of temperature drops of up to 10 K in the region 10–100 AU that possibly generate narrow heat transition barriers prone to trap planets.
