Gravitational collapse of dense cores.

• Gravitational collapse of cores - Virial Theorem

• Jeans Mass/Radius equations and examples based on actual conditions for the collapsing clouds.

• Bonnor-Ebert Mass

• Fragmentation during collapse

• Conditions for max. Fragmentation: Isothermal vs Adiabatic and discussion on what other important physical processes could be important but initially neglected, e.g. magnetic fields and rotation.

• Discussed that more detailed models set a limit for max fragmentation on  0.01 M⊙.
