Spitzer IRS mapping of the central kpc of Centaurus A
Alice C. Quillen, Joss Bland-Hawthorn, Joel Green +6
We report on the results of infrared spectroscopic mapping observations carried out in the nuclear region of Centaurus A (NGC5128). The 500 pc bipolar dust shell discovered by Quil…
Crystalline silicates and dust processing in the protoplanetary disks of the Taurus young cluster
Dan M. Watson, Jarron M. Leisenring, Elise Furlan +15
We characterize the crystalline silicate content and spatial distribution of small dust grains in a large sample of protoplanetary disks in the Taurus-Auriga young cluster, using S…
Spitzer observations of hydrogen deuteride
David A. Neufeld, Joel D. Green, David J. Hollenbach +7
We report the detection of interstellar hydrogen deuteride (HD) toward the supernova remnant IC443, and the tentative detection of HD toward the Herbig Haro objects HH54 and HH7 an…
Spitzer observations of HH54 and HH7-11: mapping the H2 ortho-to-para ratio in shocked molecular gas
David A. Neufeld, Gary J. Melnick, Paule Sonnentrucker +6
We report the results of spectroscopic mapping observations carried out toward the Herbig-Haro objects HH7-11 and HH54 over the 5.2 - 37 micron region using the Infrared Spectrogra…
The Truncated Disk of CoKu Tau/4
Paola D'Alessio, Lee Hartmann, Nuria Calvet +11
We present a model of a dusty disk with an inner hole which accounts for the Spitzer Space Telescope Infrared Spectrograph observations of the low-mass pre-main sequence star CoKu…
