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...
