On the methanol emission detection in the TW Hya disc: the role of grain surface chemistry and non-LTE excitation [PDF]
, 2017 The recent detection of gas-phase methanol (CH$_3$OH) lines in the disc of TW Hya by Walsh et al. provided the first observational constraints on the complex O-bearing organic content in protoplanetary discs. The emission has a ring-like morphology, with

Revealing the sub-AU asymmetries of the inner dust rim in the disk around the Herbig Ae star R CrA [PDF]
, 2009 Models predict that in the innermost AU of the disk around Herbig Ae/Be star, the dust disk forms a "puffed-up" inner rim, which should result in a strongly asymmetric brightness distribution for disks seen under intermediate inclination.
