Debris Disks in Main-Sequence Binary Systems

We observed 69 A3-F8 main-sequence binary star systems using the Multiband Imaging Photometer for Spitzer on board the Spitzer Space Telescope. We find emission significantly in excess of predicted photospheric flux levels for 9 super(+4-3)% and 40 super(+7-6)% of these systems at 24 and 70 km, resp...

Description
Summary:We observed 69 A3-F8 main-sequence binary star systems using the Multiband Imaging Photometer for Spitzer on board the Spitzer Space Telescope. We find emission significantly in excess of predicted photospheric flux levels for 9 super(+4-3)% and 40 super(+7-6)% of these systems at 24 and 70 km, respectively. Twenty-two systems total have excess emission, including four systems that show excess emission at both wavelengths. A very large fraction (nearly 60%) of observed binary systems with small (
