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…
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…
A Gap with a Deficit of Large Grains in the protoplanetary disk around TW Hya
Takashi Tsukagoshi, Hideko Nomura, Takayuki Muto +7
We report 3 au resolution imaging observations of the protoplanetary disk around TW Hya at 145 and 233 GHz with the Atacama Large Millimeter/Submillimeter Array. Our observat…
Light scattering by fractal dust aggregates: I. Angular dependence of scattering
Ryo Tazaki, Hidekazu Tanaka, Satoshi Okuzumi +2
In protoplanetary disks, micron-sized dust grains coagulate to form highly porous dust aggregates. Because the optical properties of these aggregates are not completely understood,…
