Morphology of the methanol (CH3OH) emission toward TW Hya. (a) 290 GHz continuum emission from J. Huang et al. (2018) overlaid with the dust disk extent derived from our observations in J. D. Ilee et al. (2022; dashed ellipse). (b) Integrated intensity map of the ﹩0\mathop{.}\limits^{^{\prime\prime} }7﹩ stacked methanol transitions. (c)–(f) As (b), but for the individually detected transitions.
