* Higher mass: Hotter stars are generally more massive than cooler stars. This is because their greater gravitational pull leads to higher core temperatures and pressures, which fuel nuclear fusion at a faster rate, resulting in more energy output and a hotter surface.
* Shorter lifespan: Hotter stars burn through their fuel much faster than cooler stars due to their higher energy output. This means they have shorter lifespans, often measured in millions of years.
* Bluer color: The peak of their blackbody radiation spectrum falls in the blue and ultraviolet part of the electromagnetic spectrum. This is why they appear blue or white to our eyes.
* Stronger stellar winds: They have stronger stellar winds due to the intense radiation pressure pushing outwards from their surface.
* Higher luminosity: Hotter stars emit significantly more energy per unit surface area, resulting in much higher luminosity.
Note: While these characteristics are generally true, there are exceptions depending on the star's specific stage of life, its chemical composition, and other factors.
