Comparison between observed spectra of 2MASS 1507-1627 (L5) and MSG cloudy models. 2MASS 1507-1627 has an effective temperature ~1600 K (Cushing et al. 2005) and a surface gravity of about log(g)≈5.2 (Filippazzo et al. 2015). The observed data is shown in black. The NIR data (top panels) is from Cushing et al. (2005), and the MIR data (bottom panels) is from Suárez & Metchev (2022). In the left panels, the MSG model spectra shown in pink is for a model with T_eff = 1600 K, log(g)=4.0, and TiO₂ nucleation seeds. In the right panels, the MSG model spectra shown in orange is for a model with T_eff = 1600 K, log(g)=4.0 and SiO nucleation seeds. We note that, unlike other figures in the paper, here we plot the frequency dependent flux (F_ν) for a better visualisation of the silicate feature around 10 µm in the MIR.
