We have obtained Spitzer Space Telescope Multiband Imaging Photometer for Spitzer (MIPS) 24 μm and 70 μm observations of 215 nearby, Hipparcos B- and A-type common proper-motion single and binary systems in the nearest OB association, Scorpius-Centaurus. Combining our MIPS observations with those of other ScoCen stars in the literature, we estimate 24 μm B+A-type disk fractions of 17/67 (25+6 – 5%), 36/131 (27+4 – 4%), and 23/95 (24+5 – 4%) for Upper Scorpius (~11 Myr), Upper Centaurus Lupus… Expand
A Deep Spitzer Survey of Circumstellar Disks in the Young Double Cluster, h and chi Persei
We analyze very deep IRAC and MIPS photometry of $\sim$ 12,500 members of the 14 Myr old Double Cluster, h and $\chi$ Persei, building upon on our earlier, shallower Spitzer studies (Currie et al.Expand
IRS Spectra of Debris Disks in the Scorpius-Centaurus OB Association
We analyze Spitzer IRS spectra of 110 B-, A-, F-, and G-type stars with optically thin infrared excess in the Scorpius-Centaurus (ScoCen) OB association. The age of these stars ranges from 11-17 Myr.Expand
