GASEOUS MATERIAL ORBITING THE POLLUTED, DUSTY WHITE DWARF HE 1349-2305

We present new spectroscopic observations of the polluted, dusty, helium-dominated atmosphere white dwarf star HE 1349-2305. Optical spectroscopy reveals weak Ca II infrared triplet emission indicating that metallic gas debris orbits and is accreted by the white dwarf. Atmospheric abundances are mea...
