Present-day stellar mass fraction of dwarf galaxies. The filled coloured circles represent Bashful (red) and Doc (blue) simulated with the supebubble feedback. The empty circles with coloured edges correspond to Bashful (red), Doc (blue), Dopey (purple) and Grumpy (green) simulated in Shen et al. (2014), with the blastwave feedback model. The empty grey squares represent the sample of isolated dwarf galaxies analysed in Read et al. (2017). The black lines report the low-mass extrapolations of the SMHM relation provided by Behroozi et al. (2013) (solid), Moster et al. (2013) (dashed), Brook et al. (2014) (dot-dashed), and Brook et al. (2014) (dotted).
