Notes. (a)The value of the UV luminosity was estimated using the results from Yang et al. (2012) relating the far-UV luminosity to the accretion luminosity of the star (see Table 6 in that paper). The accretion luminosity was evaluated using a characteristic value of the mass accretion rate of 1.4 × 10−10 M⊙ yr−1 (e.g. Haffert et al. 2019; Thanathibodee et al. 2020) alongside Eq. (8) in Gullbring et al. (1998).(b) ‘Zone 1’ is the computational domain that hosts the inner disc plus the dust-depleted gap, while ‘Zone 2’ contains the outer disc.
