Formation and evolution of disks around young stellar objects

B Zhao, K Tomida, P Hennebelle, JJ Tobin… - Space Science …, 2020 - Springer
Recent observations have suggested that circumstellar disks may commonly form around
young stellar objects. Although the formation of circumstellar disks can be a natural result of …

The role of magnetic fields in the formation of protostellar discs

J Wurster, ZY Li - Frontiers in Astronomy and Space Sciences, 2018 - frontiersin.org
The formation of a protostellar disc is a natural outcome during the star formation process.
As gas in a molecular cloud core collapses under self-gravity, the angular momentum of the …

Protostellar collapse simulations in spherical geometry with dust coagulation and fragmentation
