* Luminosity and Surface Area: The luminosity of a star is directly related to its surface area. A larger star has a greater surface area, meaning it emits more light and energy.
* Mass and Size: A more massive star will have a larger radius (and therefore a larger surface area) due to the increased gravitational pull. This is because the greater mass creates more pressure and heat in the core, leading to a larger overall size.
* Surface Temperature: While the surface temperature remains the same, the increased surface area means more total energy is radiated.
In summary: Even though the surface temperature is constant, the increased surface area due to the larger mass will result in a greater total luminosity for the star.
