Temperature of the Core of the Sun
Core Temperature of the Sun: 15-16 Million Kelvin
The core of the Sun is an extremely hot and dense region where nuclear fusion occurs, generating the Sun's energy. The temperature in the core is estimated to be around 15 to 16 million Kelvin (K) . This intense heat is a result of the gravitational compression from the layers above and the energy produced by nuclear fusion reactions, primarily through the proton-proton (p-p) chain reaction .
Helioseismic Constraints on Core Temperature
Helioseismic studies, which analyze the propagation of sound waves within the Sun, provide constraints on the temperature and composition profiles of the solar core. These studies suggest that the central temperature of the Sun is bounded between 15.2 million K and 16.1 million K, with a central value around 15.6 million K. This range is consistent with the observed solar luminosity and the helioseismic data, indicating that the nuclear energy generation rates may need slight adjustments but do not significantly affect the core temperature estimates.
Energy Generation and Density in the Core
The core, constituting about 10% of the Sun's mass, is not only extremely hot but also very dense, with a density approximately 160 times that of water. The energy generated in the core through nuclear fusion is crucial for maintaining the Sun's structure and radiating energy outward to the solar system.
Conclusion
In summary, the core of the Sun is a region of extreme temperatures, ranging from 15 to 16 million Kelvin, driven by nuclear fusion processes and gravitational compression. Helioseismic data and solar models consistently support these temperature estimates, highlighting the core's critical role in the Sun's energy production and overall dynamics.
