文摘
- •
A model for a quasi-stationary cloud core, precursor of a collapsing core, is developed.
- •
It evaluates the core stability and the validity of the chosen equation of state (EOS).
- •
It is combined with a chemical module to compute the produced water amount.
- •
UV radiation influences the core stability and but only slightly the water amount.
- •
The likely EOS of the thermally balanced core is a modified polytropic EOS.
