What temperature range do models suggest for the cores of the most enormous stars approaching $100 M_ ext{Sun}$?
Answer
30 to 40 million Kelvin
Astrophysical models predicting the internal conditions of the largest stars, those whose masses approach one hundred times that of the Sun ($100 M_ ext{Sun}$), indicate that their central cores must achieve far higher temperatures than those of smaller stars like the Sun. These extreme temperatures, ranging between 30 million and 40 million Kelvin ($3-4 imes 10^7$ K), are necessitated by the colossal gravitational forces squeezing the stellar center. This intense pressure demands a correspondingly high rate of fusion energy production to support the star against collapse.
