e/Thermal timescale

Information
has gloss	eng: In astrophysics, the thermal time scale is an estimate of the lifetime of a star once its fuel reserves at its center are used up or if they were to disappear. Along with the nuclear and dynamical time scales, it is used to estimate the length of time a particular star will remain in a certain phase of its life and its lifespan if hypothetical conditions are met. In reality, the lifespan of a star is greater than what is estimated by the thermal time scale because as one fuel becomes scarce, another will generally take its place--hydrogen burning gives way to helium burning, which is replaced by carbon burning.
