The Frequency of Mid-Infrared Excess Sources in Galactic Surveys
B. Uzpen, H. A. Kobulnicky, A. J. Monson +27
We have identified 230 Tycho-2 Spectral Catalog stars that exhibit 8 micron mid-infrared extraphotospheric excesses in the MidCourse Space Experiment (MSX) and Spitzer Space Telesc…
HST/NICMOS Observations of NGC 1333: The Ratio of Stars to Sub-Stellar Objects
Julia Greissl, Michael R. Meyer, Bruce A. Wilking +4
We present an analysis of NICMOS photometry and low-resolution grism spectroscopy of low-mass stars and sub-stellar objects in the young star-forming region NGC 1333. Our goal is t…
Spectropolarimetry of the 3.4 micron absorption feature in NGC 1068
R. E. Mason, G. S. Wright, A. Adamson +1
In order to test the silicate-core/organic-mantle model of galactic interstellar dust, we have performed spectropolarimetry of the 3.4 micron C-H bond stretch that is characteristi…
Physical parameters of two very cool T dwarfs
D. Saumon, M. S. Marley, S. K. Leggett +8
We present new infrared spectra of the T8 brown dwarf 2MASS J04151954-0935066: 2.9-4.1 micron spectra obtained with the Infrared Camera and Spectrograph on the Subaru Telescope, an…
Initial Results from the USNO Dispersed Fourier Transform Spectrograph
Arsen R. Hajian, Bradford B. Behr, Andrew T. Cenko +15
We have designed and constructed a ``dispersed Fourier Transform Spectrometer'' (dFTS), consisting of a conventional FTS followed by a grating spectrometer. By combining these two…
Dust rings and filaments around the isolated young star V1331 Cygni
Sascha P. Quanz, Daniel Apai, Thomas Henning
We characterize the small and large scale environment of the young star V1331 Cygni with high resolution HST/WFPC2 and Digitized Sky Survey images. In addition to a previously know…
