Infrared Emission from the Dusty Disk Orbiting GD 362, an Externally Polluted White Dwarf

We report Spitzer Space Telescope photometry between 3.6 and 24 mm and spectroscopy between 5 and 15 mm of GD 362, a white dwarf with an effective temperature near 10,000 K that displays a remarkably high concentration of metals in its photosphere and a thermal infrared excess. We approximately repr...
