The chemical composition of an extrasolar minor planet.

ZUCKERMAN B., KOESTER D., MELIS C., HANSEN B.M. and JURA M.

Abstract (from CDS):

We report the relative abundances of 17 elements in the atmosphere of the white dwarf star GD 362, material that, very probably, was contained previously in a large asteroid or asteroids with composition similar to the Earth-Moon system. The asteroid may have once been part of a larger parent body not unlike one of the terrestrial planets of our solar system.
