What star is hotter but less luminous than Polaris?

The star that is hotter but less luminous than Polaris is Sirius B. While Sirius B has a surface temperature of around 25,000 K, significantly hotter than Polaris's approximately 6,000 K, it is a white dwarf and has much lower luminosity. Polaris, a supergiant star, shines brightly despite its cooler temperature due to its large size. Thus, Sirius B exemplifies the relationship between temperature and luminosity in stars.
