EXOCOMETS AT LARGE ORBITAL RADII AND THEIR INWARD TRANSPORT IN DEBRIS DISCS
… within these belts grind down solids producing dust and giving rise to debris discs. Primitive asteroids and comets likely played a major role in the emergence of life on Earth through their delivery of volatiles early in the lifetime of our planet. Cometary impacts, therefore, could be a …
