A Spitzer search for cold dust within globular clusters
P. Barmby, M. L. Boyer, C. E. Woodward +5
Globular cluster stars evolving off the main sequence are known to lose mass, and it is expected that some of the lost material should remain within the cluster as an intracluster…
Spitzer/IRAC Observations of AGB stars
Massimo Marengo, Megan Reiter, Giovanni G. Fazio
We present here the first observation of galactic AGB stars with the InfraRed Array Camera (IRAC) onboard the Spitzer Space Telescope. Our sample consists of 48 AGB stars of differ…
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…
Spitzer/IRAC Characterization of Galactic AGB Stars
M. Marengo, J. L. Hora, P. Barmby +4
The Spitzer Space Telescope and in particular its InfraRed Array Camera (IRAC) is an ideal facility to study the distribution of AGB stars in our own and other galaxies because of…
Discovery of Two T Dwarf Companions with the Spitzer Space Telescope
K. L. Luhman, B. M. Patten, M. Marengo +12
We report the discovery of T dwarf companions to the nearby stars HN Peg (G0V, 18.4 pc, ~0.3 Gyr) and HD 3651 (K0V, 11.1 pc, ~7 Gyr). During an ongoing survey of 5'x5' fields surro…
