THE RISE AND FALL OF DEBRIS DISKS: MIPS OBSERVATIONS OF h AND χ PERSEI AND THE EVOLUTION OF MID-IR EMISSION FROM PLANET FORMATION

摘要

We describe Spitzer MIPS observations of the double cluster, h and χ Persei, covering a ～0.6 deg~2 area surrounding the cores of both clusters. The data are combined with IRAC and 2MASS data to investigate ～616 sources from 1.25-24 μm. We use the long-bas
