Physics

Scientific paper

We propose to search the brightest disk-polluted white dwarf G29-38 at MIPS 70 um to directly test for a cold asteroid belt whose existence is inferred from successful modeling of its atmosphere and innermost circumstellar region. The metal-enriched photosphere and warm 2-24 um excess at G29-38 is well reproduced by a flat ring resulting from a tidally-disrupted minor planet perturbed into a close orbit. We construct a model of a surviving asteroid belt at 10 AU in which there is a 500 Myr accumulation of particles similar in nature to the solar zodiacal dust, which cannot be removed by drag forces at this low luminosity degenerate. Using this model, we predict a 70 um flux density of at least 2.4 mJy which should be detectable at the 4 sigma level in 1.7 hours of total telescope time.
