Knowing the following information: Sun surface temperature of 5788 K, Sun's core is between 20-25% of radius. I tried to (perhaps naively) calculate the temperature to the edge of its core from the surface temperature, using an inverse square law. Depending on which value you use for the core radius, 0.2^2 or 0.25^2, you get a temperature between 92,608 to 144,700 K, which is well below the known value of 15 million K. So what went wrong?
