Time evolution of system 0004 from RUN-2 “MHD”. Top left panel: stellar mass, disc mass and, cumulative mass removed from the disc by fragmentation. Middle left panel: accretion and outflow rates. Bottom left panel: stellar luminosity. Top right panel: surface density at different times. Middle right panel: midplane temperature at different times. Bottom left panel: stellar luminosity (accretion and intrinsic). Bottom right panel: contour plot of the surface density with fragmentation criteria (see main text). The black vertical lines denote, in order of increasing time: t_infall ≈ 1.02 kyr, t_pms ≈0.75 Myr and t_NIR ≈ 0.95 Myr (see Sect. 4).
