radiative

The result is that a star’s convective zone can be partially transformed into a radiative zone.

The rate of fusion creates two different zones within a star, radiative zones and convective zones.

It may be connected with the radiative intensity of the star, or its age, or both.

Both surfaces appear to be metallic; what, then, is the cause of the observed difference in their radiative power?

Determining, moreover, the absorptive power of those powders, it is found to go hand-in-hand with their radiative power.

Equally important is the inquiry into the mechanism of radiative equilibrium in sun and stars.

Sirius itself, on the other hand, possesses a far higher radiative intensity than our sun.
