Same as in Fig. 6, but for normalised data: Ṁacc normalised by the time factor provided by Hartmann et al. (1998)Ṁacc evolution models (~ t− η, see text) vs. M∗ (right) and Ṁacc normalised by M∗β vs. age (right; Ṁacc evolution curves by Hartmann et al. are also normalised). The best-fit relationships we obtain are indicated with a solid red line and correspond to power-law indexes β = 2.2 (left) and η = 1.6 (right). The vertical dotted line in the right graph shows the lower limit on age that we considered for the fit of the power-law decrement. The position of the outbursting source V2775 Ori (Paper II, Caratti o Garatti et al. 2011) is marked by an arrow in the temporal evolution plot.
