| 1 | High statistics search for ultrahigh energy gamma-ray emission from Cygnus X-3 and Hercules X-1 | Kieda, David B. | We have carried out a high statistics (2 X 10 9 events) search for ultrahigh energy g-ray emission from the x-ray binary sources Cygnus X-3 and Hercules X-1. Using data taken with the CASA-MIA detector over a five year period (1990-1995), we find no evidence for steady emission from either source.

| 2 | Rise and fall of debris disks: MIPS observations of h and chi Persei and the evolution of mid-IR emission from planet formation | Bromley, Benjamin C. | We describe Spitzer MIPS observations of the double cluster, h and X Persei, covering a 0.6 deg2 area surrounding the cores of both clusters. The data are combined with IRAC and 2MASS data to investigate 616 sources from 1.25Y24 m. We use the long-baseline Ks ½24 color to identify two population... | Infrared circumstellar matter; Open clusters and associations stars: Individual (NGC 869, NGC 884) planetary systems: Formation, planetary systems: Protoplanetary disks | 2008 |
