Abstract

We present mid-infrared photometry of 124 white dwarf stars with the Spitzer Space Telescope . Objects were observed simultaneously at 4.5 and 8.0 μm with sensitivities better than 0.1 mJy. This data set can be used to test models of white dwarf atmospheres in a new wavelength regime, as well as to search for planetary companions and debris disks.
