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

An ALMA Survey of Protoplanetary Disks in the $\sigma$ Orionis Cluster [PDF]
, 2017 The $\sigma$ Orionis cluster is important for studying protoplanetary disk evolution, as its intermediate age ($\sim$3-5 Myr) is comparable to the median disk lifetime. We use ALMA to conduct a high-sensitivity survey of dust and gas in 92 protoplanetary

Constraints on the height of the inner disk rim in pre-main-sequence stars
, 2014 The structure of inner region of protoplanetary disks around young pre-main-sequence stars is still poorly understood. This part of the disk is shaped by various forces that influence dust and gas dynamics, and by dust sublimation, which creates abrupt ...
