Calibration and flight performance of the long-slit imaging dual order spectrograph
Roxana E. Lupu, Stephan R. McCandliss, Brian Fleming +3
We present a preliminary calibration and flight performance of the Long-Slit Imaging Dual Order Spectrograph (LIDOS), a rocket-borne instrument with a large dynamic range in the 90…
A Low-Mass H2 Component to the AU Microscopii Circumstellar Disk
Kevin France, Aki Roberge, Roxana E. Lupu +2
We present a determination of the molecular gas mass in the AU Microscopii circumstellar disk. Direct detection of a gas component to the AU Mic disk has proven elusive, with upper…
A Cometary Bow Shock and Mid-Infrared Emission Variations Revealed in Spitzer Observations of HD 34078 and IC 405
Kevin France, Stephan R. McCandliss, Roxana E. Lupu
We present new infrared observations of the emission/reflection nebula IC 405 obtained with the Spitzer Space Telescope. Infrared images in the four IRAC bands (3.6, 4.5, 5.8, and…
Discovery of Lyman-alpha Pumped Molecular Hydrogen Emission in the Planetary Nebulae NGC 6853 and NGC 3132
R. E. Lupu, K. France, S. R. McCandliss
We report the first observation of Ly pumped molecular hydrogen emission lines in planetary nebulae. The H emission observed in the ultraviolet spectra of NGC 6853 and NGC…
Molecular Hydrogen in Orion as Observed by the Far Ultraviolet Spectroscopic Explorer
K. France, S. R. McCandliss
Diffuse far-ultraviolet stellar emission scattered by dust grains has been observed in a region near the Orion Nebula. In addition to the scattered stellar continuum, emission and…
Fluorescent Molecular Hydrogen Emission in IC 63: FUSE, HUT, and Rocket Observations
K. France, B-G Andersson, S. R. McCandliss +1
We present far-ultraviolet observations of IC 63, an emission/reflection nebula illuminated by the B0.5IV star gamma Cassiopeia, located 1.3 pc from the nebula. Molecular hydrogen…
