Infrared Spectroscopy of HR 4796A's Bright Outer Cometary Ring + Tenuous Inner Hot Dust Cloud
Carey M. Lisse, Mike L. Sitko, Massimo Marengo +4
We have obtained new NASA IRTF SpeX spectra of the HR 4796A debris ring system. We find a unique red excess flux that extends out to ~9 um in Spitzer IRS spectra, where thermal emi…
Spitzer Evidence for a Late Heavy Bombardment and the Formation of Urelites in η Corvi at ~1 Gyr
C. M. Lisse, M. C. Wyatt, C. H. Chen +7
We have analyzed Spitzer and NASA/IRTF 2 - 35 \mum spectra of the warm, ~350 K circumstellar dust around the nearby MS star η Corvi (F2V, 1.4 \pm 0.3 Gyr). The spectra show clear e…
MBM 12: young protoplanetary discs at high galactic latitude
G. Meeus, A. Juhasz, Th. Henning +6
(abridged) We present Spitzer infrared observations to constrain disc and dust evolution in young T Tauri stars in MBM 12, a star-forming cloud at high latitude with an age of 2 My…
Spitzer/MIPS Observations of Stars in the Beta Pictoris Moving Group
L. M. Rebull, K. R. Stapelfeldt, M. W. Werner +7
We present Multiband Imaging Photometer for Spitzer (MIPS) observations at 24 and 70 microns for 30 stars, and at 160 microns for a subset of 12 stars, in the nearby (~30 pc), youn…
The Dust and Gas Around beta Pictoris
C. H. Chen, A. Li, C. Bohac +12
We have obtained Spitzer IRS 5.5 - 35 micron spectroscopy of the debris disk around beta Pictoris. In addition to the 10 micron silicate emission feature originally observed from t…
Mid-infrared spectra of PAH emission in Herbig AeBe stars
G. C. Sloan, L. D. Keller, W. J. Forrest +16
We present spectra of four Herbig AeBe stars obtained with the Infrared Spectrograph (IRS). on the Spitzer Space Telescope. All four of the sources show strong emission from polycy…
