Near the core, what is the approximate temperature reached within the radiative zone?
Answer
Around $7$ million Kelvin ($7 imes 10^6 ext{ K}$)
The conditions in the radiative zone are characterized by extreme heat, necessary to maintain the plasma state and drive the energy transport process. While the entire zone reaches temperatures in the millions of Kelvin, the hottest point is located at the inner boundary, immediately adjacent to the fusion-producing core. At this interface, the temperature is stated to reach roughly 7 million Kelvin, or $7 imes 10^6 ext{ K}$. This intense heat ensures the material remains highly ionized, but the density is high enough to suppress bulk convection, reinforcing the need for radiative transfer.
