How do stars form? The Sun is old and in Hydrostatic and
Thermal equilibrium. How did it get that way? This lecture
presents the basic steps of star formation as a progress from
cold interstellar Giant Molecular Clouds to Protostars in
Hydrostatic Equilibrium, and then Pre-Main Sequence evolution
which ends in ignition of core Hydrogen fusion and establishing
Thermal Equilibrium on the Zero-Age Main Sequence.
