Abstract

We investigate the sublimation effect on dust-deblis disks. We assume a constant dust production. When we consider migration of dust grains only due to Poynting-Robertson effect, the surface number density is constant for radial distance. The sublimation effect slow down the migration due to Poynting-Robertson drag and dust grains accumulate in the sublimation region. As a result, the surface number density in the region is about 10 times higher than that in outer region.
