Terrestrial planet frequency estimated from white dwarf debris discs

Post by Lazarus on 1st November 2010, 5:33 pm

Review of observations of white dwarf debris discs. The frequency of remnants of terrestrial planet systems around white dwarfs is estimated to be likely around 20-30%. This suggests that terrestrial planet formation may be quite a common occurrence around A-F type stars.
