The luminosity, surface temperature, and radius of a main-sequence star are all directly related to its mass. A greater mass leads to a greater luminosity due to the increased fusion rate in the star's core. The surface temperature would also increase due to the increased energy output, and the radius would increase due to a higher pressure in the star's core. Therefore, all three parameters would be greater in a main-sequence star with greater mass.
