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…
[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…
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…
R=100,000 Mid-IR Spectroscopy of UCHII Regions: High Resolution is Worth it!
D. T. Jaffe, Q. Zhu, J. H. Lacy +2
Ultracompact HII regions are signposts of massive star formation and their properties provide diagnostics for the characteristics of very young O stars embedded in molecular clouds…
H2 Mid-IR Pure Rotational Emission from Young Stars: The TEXES/IRTF Survey
Matthew J. Richter, John H. Lacy, Thomas K. Greathouse +2
We describe the TEXES survey for mid-IR H2 pure rotational emission from young stars and report early successes. H2 emission is a potential tracer of warm gas in circumstellar disk…
