Scientific paper

We propose to observe six externally-polluted white dwarfs with dust disks to measure accurate abundances of volatile elements, especially carbon and sulfur. These data will enable us to determine whether the minor planets now being accreted onto the target white dwarfs more resemble primitive meteorites such as CI chondrites or more resemble bulk Earth.;
