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…
A potential new method for determining the temperature of cool stars
S. Viti, H. R. A. Jones, M. J. Richter +3
We present high resolution (R = 90,000) mid-infrared spectra of M dwarfs. The mid infrared region of the spectra of cool low mass stars contain pure rotational water vapour transit…
[Ne II] Observations of Gas Motions in Compact and Ultracompact H II Regions
Qingfeng Zhu, John H. Lacy, Daniel T. Jaffe +2
We present high spatial and spectral resolution observations of sixteen Galactic compact and ultracompact H II regions in the [Ne II] 12.8 microns fine structure line. The small th…
Mid-Infrared Photometry and Spectra of Three High Mass Protostellar Candidates at IRAS 18151-1208 and IRAS 20343+4129
M. F. Campbell, T. K. Sridharan, H. Beuther +8
We present arcsecond-scale mid-ir photometry (in the 10.5 micron N band and at 24.8 microns), and low resolution spectra in the N band (R~100) of a candidate high mass protostellar…
TEXES Observations of Pure Rotational H2 Emission From AB Aurigae
M. A. Bitner, M. J. Richter, J. H. Lacy +3
We present observations of pure rotational molecular hydrogen emission from the Herbig Ae star, AB Aurigae. Our observations were made using the Texas Echelon Cross Echelle Spectro…
Mass Flows in Cometary UCHII Regions
Qing-Feng Zhu, John H. Lacy, Daniel T. Jaffe +2
High spectral and spatial resolution, mid-infrared fine structure line observations toward two ultracompact HII (UCHII) regions (G29.96 -0.02 and Mon R2) allow us to study the stru…
