Stars with higher surface temperatures than the Sun are classified as blue stars or white stars. Here's a breakdown:

* Blue Stars: These are the hottest stars, with surface temperatures ranging from 25,000 to 50,000 Kelvin (K). They emit a blue-white light due to the high energy of their radiation. Examples include Rigel (in Orion) and Spica (in Virgo).

* White Stars: These stars have surface temperatures between 7,500 and 10,000 K. They appear white or slightly bluish-white. Examples include Sirius (the brightest star in the night sky) and Vega (in Lyra).

The Sun's surface temperature is around 5,500 K, which makes it a yellow dwarf star.

Here's a quick comparison:

| Star Type | Surface Temperature (K) | Color |

|---|---|---|

| Blue Stars | 25,000 - 50,000 | Blue-white |

| White Stars | 7,500 - 10,000 | White or slightly bluish-white |

| Yellow Dwarf Stars (like our Sun) | 5,500 | Yellow |

Remember: The color of a star is a good indicator of its surface temperature. Hotter stars emit more blue light, while cooler stars emit more red light.
