Opacity vs density
WebPage ‹#› AS 3003 Stellar Physics 6.2 Opacity in stellar interiors •Opacity depends on: –Level populations of different ion species (bb,bf) –Ionization balance (bf,ff) –Electron density ne (bf,ff,es) •LTE is a good approximation inside stars. •Level populations of individual species depend on T (Boltzmann) and on degree of ionization. •Degree of … The words "opacity" and "opaque" are often used as colloquial terms for objects or media with the properties described above. However, there is also a specific, quantitative definition of "opacity", used in astronomy, plasma physics, and other fields, given here. In this use, "opacity" is another term for the mass attenuation coefficient (or, depending on context, mass absorption coefficient, the difference is described here) at a particular frequency of electro…
