R=100,000 Spectroscopy of Photodissociation Regions: H2 Rotational Lines in the Orion Bar
Katelyn N. Allers, Daniel T. Jaffe, John H. Lacy +1
Ground state rotational lines of H2 are good temperature probes of moderately hot (200-1000 K) gas. The low A-values of these lines result in low critical densities while ensuring…
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…
