The evolution and delivery of rocky extra-solar materials to white dwarfs
The most direct and substantial way to measure the geochemistry of extrasolar objects is to
perform chemical autopsies on their broken-up remains. However, traditional ways of …

The frequency of gaseous debris discs around white dwarfs
ABSTRACT A total of 1–3 per cent of white dwarfs are orbited by planetary dusty debris
detectable as infrared emission in excess above the white dwarf flux. In a rare subset of …
