Hi,
I'm wondering why the Sun's luminosity has increased over time.
I have learned that every star in the main sequence also tend to increase their luminosity but I haven't figured out why.
Luminosity is related to star's radius and temperature so does these parameters rise during the star's main sequence?
That would explain the whole thing but does it work on highly massive stars which decrease their temperature?
Do these giant stars increase their radius to rise the luminosity?
