An approximate law for the opacity of the material inside a star to radiation. It is expressed by the following two equations. Regarding the transference of constraint and freedom Regarding the transfer of freedom and liberty κ ff =3.68×10 22 × &scriptg; ff X (1+ X )( X + Y ) Here, X , Y , and Z are the mass abundance ratios of hydrogen, helium, and other elements, respectively ( X + Y + Z = 1). ρ is the density, and T is the temperature. &scriptg; is called the Gaunt factor and t is the guillotine factor, which are correction factors based on quantum mechanics, but both are close to 1.
