Variations of the 10 um Silicate Features in the Actively Accreting T Tauri Stars: DG Tau and XZ Tau (2009)

Bary, Jeffrey S., Leisenring, Jarron M., Skrutskie, Michael F.

Using the Infrared Spectrograph aboard the Spitzer Space Telescope, we observed multiple epochs of 11 actively accreting T Tauri stars in the nearby Taurus-Auriga star forming region. In total, 88...

Interferometric evidence for resolved warm dust in the DQ Tau system (2009)

Boden, Andrew F., Akeson, Rachel L., Sargent, Anneila I., Carpenter, John M., Ciardi, David R., Bary, Jeffrey S., ...

We report on near-infrared (IR) interferometric observations of the double-lined pre-main sequence binary system DQ Tau. We model these data with a visual orbit for DQ Tau supported by the...

Physical Conditions of Accreting Gas in T Tauri Star Systems (2008)

Bary, Jeffrey S., Matt, Sean P., Skrutskie, Michael F., Wilson, John C., Peterson, Dawn E., Nelson, Matthew J.

We present results from a low resolution (R~300) near-infrared spectroscopic variability survey of actively accreting T Tauri stars (TTS) in the Taurus-Auriga star forming region. Paschen and...

Quiescent H2 Emission From Pre-Main Sequence Stars in Chamaeleon I (2008)

Bary, Jeffrey S., Weintraub, David A., Shukla, Sonali J., Leisenring, Jarron M., Kastner, Joel H.

We report the discovery of quiescent emission from molecular hydrogen gas located in the circumstellar disks of six pre-main sequence stars, including two weak-line T Tauri stars (TTS), and one...

Detection of Molecular Hydrogen Orbiting a "Naked" T Tauri Star (2002)

Bary, Jeffrey S., Weintraub, David A., Kastner, Joel H.

Astronomers have established that for a few million years newborn stars possess disks of orbiting gas and dust. Such disks, which are likely sites of planet formation, appear to disappear once these...
