Solar abundances of rock-forming elements, extreme oxygen and hydrogen in a young polluted white dwarf

Solar abundances of rock-forming elements, extreme oxygen and hydrogen in a young polluted white dwarf

The T-eff = 20 800 K white dwarf WD 1536+520 is shown to have broadly solar abundances of the major rock-forming elements O, Mg, Al, Si, Ca, and Fe, together with a strong relative depletion in the volatile elements C and S. In addition to the highest metal abundances observed to date, including log...
