In the Figure Shown Below, the Portion of the H-R

Question 67

Essay

In the figure shown below, the portion of the H-R diagram corresponding to the Hayashi track
of a 1 MSUN star is shown.Temperature increases toward the left, and luminosity increases toward the top of the diagram.Even though the temperature of the protostar is hardly changing as it approaches the main sequence, its luminosity is decreasing.Why? In the figure shown below, the portion of the H-R diagram corresponding to the Hayashi track of a 1 M<sub>SUN</sub> star is shown.Temperature increases toward the left, and luminosity increases toward the top of the diagram.Even though the temperature of the protostar is hardly changing as it approaches the main sequence, its luminosity is decreasing.Why?
