Magnetohydrodynamical modeling of star-disk formation: from isolated spherical collapse towards incorporation of external dynamics

M Kuffmeier - Frontiers in Astronomy and Space Sciences, 2024 - frontiersin.org
The formation of protostars and their disks has been understood as the result of the
gravitational collapse phase of an accumulation of dense gas that determines the mass …
