The TEXES Survey For H2 Emission From Protoplanetary Disks
M. A. Bitner, M. J. Richter, J. H. Lacy +9
We report the results of a search for pure rotational molecular hydrogen emission from the circumstellar environments of young stellar objects with disks using the Texas Echelon Cr…
UV excess measures of accretion onto young very low-mass stars and brown dwarfs
Gregory J. Herczeg, Lynne A. Hillenbrand
Low-resolution spectra from 3000-9000 AA of young low-mass stars and brown dwarfs were obtained with LRIS on Keck I. The excess UV and optical emission arising in the Balmer and Pa…
High-resolution Spectroscopy of [Ne II] Emission from TW Hya
Gregory J. Herczeg, Joan Najita, Lynne A. Hillenbrand +1
We present high-resolution echelle spectra of [Ne II] 12.81 micron emission from the classical T Tauri star (CTTS) TW Hya obtained with MICHELLE on Gemini North. The line is center…
Detection of [Ne II] Emission from Young Circumstellar Disks
I. Pascucci, D. Hollenbach, J. Najita +9
We report the detection of [Ne II] emission at 12.81 micron in four out of the six optically thick dust disks observed as part of the FEPS Spitzer Legacy program. In addition, we d…
How Hot is the Wind from TW Hydrae?
C. M. Johns-Krull, G. J. Herczeg
It has recently been suggested that the winds from Classical T Tauri stars in general, and the wind from TW Hya in particular, reaches temperatures of at least 300,000 K while main…
Formation and Evolution of Planetary Systems: Upper Limits to the Gas Mass in Disks Around Sun-like Stars
I. Pascucci, U. Gorti, D. Hollenbach +17
We have carried out a sensitive search for gas emission lines at infrared and millimeter wavelengths for a sample of 15 young sun-like stars selected from our dust disk survey with…
