People also ask are hotter stars brighter?

Stars on the Main Sequence that are hotter than the Sun are also larger than the Sun. So hot blue stars are more luminous (and therefore appear higher in this diagram) for two reasons: they are hotter, and hot objects are more luminous than cool objects, but they are also larger. Regarding this, what relationship do you see between star color and star temperature? There is no relationship of a star's color and temperature. Red/Orange stars are the coolest and blue stars are the hottest; As stars grow hotter, their temperature changes from Red/Orange to Blue.

Does temperature affect star brightness?

Luminosity Is Caused By... That increased surface area allows more light and energy to be given off. Temperature also affects a star's luminosity. As a star gets hotter, the number of nuclear reactions increases. More reactions, more energy. Subsequently, what is a bright star? The brightest star in the sky is Sirius, also known as the "Dog Star" or, more officially, Alpha Canis Majoris, for its position in the constellation Canis Major. Sirius is a binary star dominated by a luminous main sequence star, Sirius A, with an apparent magnitude of -1.46.

Correspondingly, which star is brighter antares or betelgeuse? Both stars are typical massive M2 supergiant stars, 500-600 light years away. Betelgeuse is slightly brighter (V = 0.45), perhaps because it is slightly more luminous.
