Explanation: Even for the best studied star we can only measure 4 parameters: mass, luminosity, radius and chemical composition of the outer layers. We can determine the structure of the star with these parameters, because we have one more condition: the constancy of the stars over long periods of time. Even variable stars have long-term stability of the average structure. The existence of fossil algae on the earth over 1 billion years old and fossils up to 3.5 billion years old is evidence that the temperature of the earth cannot have changed by more than about 20 ° C. Therefore, the interior of the stars must be in perfect balance.
