Astronomers observing the molecular cloud Barnard 68 detect a dense region of interstellar gas and dust undergoing gravitational contraction.
Describe the thermodynamic and nuclear processes that occur as this contracting cloud transitions into a stable main sequence star, explaining how hydrostatic equilibrium is established.
