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…
Hot Gas Lines in T Tauri Stars
David R. Ardila, Gregory J. Herczeg, Scott G. Gregory +20
For Classical T Tauri Stars (CTTSs), the resonance lines of N V, Si IV, and C IV, as well as the He II 1640 A line, act as diagnostics of the accretion process. Here we assemble a…
Resolving the gap and AU-scale asymmetries in the pre-transitional disk of V1247 Orionis
Stefan Kraus, Michael J. Ireland, Michael L. Sitko +10
Pre-transitional disks are protoplanetary disks with a gapped disk structure, potentially indicating the presence of young planets in these systems. In order to explore the structu…
Characterizing the stellar photospheres and near-infrared excesses in accreting T Tauri systems
M. K. McClure, N. Calvet, C. Espaillat +6
Using NASA IRTF SpeX data from 0.8 to 4.5 m, we determine self-consistently the stellar properties and excess emission above the photosphere for a sample of classical T Tauri st…
Transitional disks and their origins: an infrared spectroscopic survey of Orion A
K. H. Kim, Dan M. Watson, P. Manoj +10
Transitional disks are protoplanetary disks around young stars, with inner holes or gaps which are surrounded by optically thick outer, and often inner, disks. Here we present obse…
Accretion Rates for T Tauri Stars Using Nearly Simultaneous Ultraviolet and Optical Spectra
Laura Ingleby, Nuria Calvet, Gregory Herczeg +9
We analyze the accretion properties of 21 low mass T Tauri stars using a dataset of contemporaneous near ultraviolet (NUV) through optical observations obtained with the Hubble Spa…
