Polycyclic Aromatic Hydrocarbons Orbiting HD 233517, an Evolved Oxygen-Rich Red Giant
M. Jura, J. Bohac, B. Sargent +7
We report spectra obtained with the Spitzer Space Telescope in the 5 to 35 micron range of HD 233517, an evolved K2 III giant with circumstellar dust. At wavelengths longer than 13…
The Chandra XBootes Survey - III: Optical and Near-IR Counterparts
Kate Brand, Michael J. I. Brown, Arjun Dey +14
The XBootes Survey is a 5-ks Chandra survey of the Bootes Field of the NOAO Deep Wide-Field Survey (NDWFS). This survey is unique in that it is the largest (9.3 deg^2), contiguous…
Formation and Evolution of Planetary Systems (FEPS): Primordial Warm Dust Evolution From 3-30 Myr around Sun-like Stars
M. D. Silverstone, M. R. Meyer, E. E. Mamajek +14
We present data obtained with the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope (Spitzer) for a sample of 74 young (t < 30 Myr old) Sun-like (0.7 < M(star)/M(Sun)…
An 850 micron survey for dust around solar mass stars
Joan Najita, Jonathan P. Williams
We present the results of an 850 micron JCMT/SCUBA survey for dust around 13 nearby solar mass stars. The dust mass sensitivity ranged from 0.005 to 0.16 Earth masses. Three source…
The XBootes Chandra Survey Paper II: The X-ray Source Catalog
Almus Kenter, Stephen S. Murray, William R. Forman +14
We present results from a Chandra survey of the nine square degree Bootes field of the NOAO Deep Wide-Field Survey (NDWFS). This XBootes survey consists of 126 separate contiguous…
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…
Formation and Evolution of Planetary Systems: Cold Outer Disks Associated with Sun-like stars
Jinyoung Serena Kim, Dean C. Hines, Dana E. Backman +24
We present the discovery of debris systems around three solar mass stars based upon observations performed with the Spitzer Space Telescope as part of a Legacy Science Program, ``t…
Formation and Evolution of Planetary Systems: Upper Limits the Gas Mass in HD105
D. Hollenbach, U. Gorti, M. Meyer +13
We report infrared spectroscopic observations of HD 105, a nearby ( pc) and relatively young ( Myr) G0 star with excess infrared continuum emission, which has bee…
XBootes: An X-Ray Survey of the NDWFS Bootes Field - Paper I Overview and Initial Results
Stephen S. Murray, Almus Kenter, William R. Forman +14
We obtained a 5 ksec deep Chandra X-ray Observatory ACIS-I map of the 9.3 square degree Bootes field of the NOAO Deep Wide-Field Survey. Here we describe the data acquisition and a…
Tracing the Nuclear Accretion History of the Red Galaxy Population
Kate Brand, Arjun Dey, Michael J. I. Brown +14
We investigate the evolution of the hard X-ray luminosity of the red galaxy population using a large sample of 3316 red galaxies selected over a wide range in redshift (0.3<z<0.9)…
