The term Eddington valve has been used for this mechanism, but this is increasingly obsolete. [1] Here, the Greek letter kappa (κ) is used to indicate the radiative opacity at any particular depth of the stellar ...

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 ) κ ν {\displaystyle \kappa _{\nu }} at ...
