Behind the scenes of protostellar disc formation

For a long time the formation of protostellar discs — a prerequisite to the formation of planetary systems — has defied theoretical astrophysicists. Now, researchers have made a breakthrough in our understanding of how protoplanetary discs form, demonstrating that chemistry and microphysics are crucial to the fundamental processes underlying star and planet formation.

Adding a new dimension to the early chemistry of the solar system

An international research team has used sophisticated computer simulations to calculate a two-dimensional map of the dust chemistry in the solar nebula, the thin dusty disc that surrounded the young Sun and out of which the planets formed. The study has given new insights into the chemical composition of the dust grains that formed in the solar system 4.5 billion years ago.
