A Herschel view of protoplanetary disks in the Ori cluster
Karina Maucó, Jesús Hernández, Nuria Calvet +6
We present new Herschel PACS observations of 32 T Tauri stars in the young (3 Myr) Ori cluster. Most of our objects are K & M stars with large excesses at 24 m. We use…
The Transitional Disk around IRAS 04125+2902
C. Espaillat, S. Andrews, D. Powell +4
Resolved submillimeter imaging of transitional disks is increasingly revealing the complexity of disk structure. Here we present the first high-resolution submillimeter image of a…
Detections of trans-Neptunian ice in protoplanetary disks
M. K. McClure, C. Espaillat, N. Calvet +6
We present Herschel Space Observatory PACS spectra of T Tauri stars, in which we detect amorphous and crystalline water ice features. Using irradiated accretion disk models, we det…
Curved walls: Grain growth, settling, and composition patterns in T Tauri disk dust sublimation fronts
M. K. McClure, P. D'Alessio, N. Calvet +6
The dust sublimation walls of disks around T Tauri stars represent a directly observable cross-section through the disk atmosphere and midplane. Their emission properties can probe…
Mineral Processing by Short Circuits in Protoplanetary Disks
Colin P. McNally, Alexander Hubbard, Mordecai-Mark Mac Low +2
Meteoritic chondrules were formed in the early solar system by brief heating of silicate dust to melting temperatures. Some highly refractory grains (Type B calcium-aluminum-rich i…
Wall emission in circumbinary disks: the case of CoKu Tau/4
Erick Nagel, Paola D'Alessio, Nuria Calvet +4
A few years ago, the mid-IR spectrum of a Weak Line T Tauri Star, CoKu Tau/4, was explained as emission from the inner wall of a circumstellar disk, with the inner disk truncated a…
