Grand challenges in protoplanetary disc modelling
Thomas J. Haworth, John D. Ilee, Duncan H. Forgan +18
The Protoplanetary Discussions conference --- held in Edinburgh, UK, from 7th --11th March 2016 --- included several open sessions led by participants. This paper reports on the di…
ALMA reveals the anatomy of the mm-sized dust and molecular gas in the HD 97048 disk
Catherine Walsh, Attila Juhász, Gwendolyn Meeus +5
Transitional disks show a lack of excess emission at infrared wavelengths due to a large dust cavity, that is often corroborated by spatially resolved observations at ~ mm waveleng…
Cometary ices in forming protoplanetary disc midplanes
Maria N. Drozdovskaya, Catherine Walsh, Ewine F. van Dishoeck +5
Low-mass protostars are the extrasolar analogues of the natal Solar System. Sophisticated physicochemical models are used to simulate the formation of two protoplanetary discs from…
Setting the volatile composition of (exo)planet-building material. Does chemical evolution in disk midplanes matter?
Christian Eistrup, Catherine Walsh, Ewine F. van Dishoeck
[Abridged] Chemical evolution in the protoplanetary disk midplane can modify the composition of ices and gases. We have investigated if and how chemical evolution affects the abund…
First detection of gas-phase methanol in a protoplanetary disk
Catherine Walsh, Ryan A. Loomis, Karin I. Oberg +7
The first detection of gas-phase methanol in a protoplanetary disk (TW Hya) is presented. In addition to being one of the largest molecules detected in disks to date, methanol is a…
Candidate Water Vapor Lines to Locate the HO Snowline through High-Dispersion Spectroscopic Observations I. The Case of a T Tauri Star
Shota Notsu, Hideko Nomura, Daiki Ishimoto +4
Inside the HO snowline of protoplanetary disks, water evaporates from the dust-grain surface into the gas phase, whereas it is frozen out on to the dust in the cold region be…
Chemical complexity in protoplanetary disks in the era of ALMA and Rosetta
Catherine Walsh
Comets provide a unique insight into the molecular composition and complexity of the material in the primordial solar nebula. Recent results from the Rosetta mission, currently mon…
