A red star near the end of its life is cooler and is called a red giant.
A white star in the middle of its life, like our sun, is a very hot ball of gas.
The surface temperature of white dwarf stars is generally higher than that of red supergiants. White dwarfs typically have temperatures ranging from about 5,000 to 100,000 Kelvin, while red supergiants usually have surface temperatures between 3,000 and 4,500 Kelvin. This significant difference is due to the evolutionary stages these stars occupy, with white dwarfs being the remnants of stars that have exhausted their nuclear fuel, while red supergiants are in a later phase of stellar evolution.

Well, let me tell you, it's truly fascinating! White dwarfs are actually much smaller and cooler than supergiants, so they seem dimmer to our eyes. But despite their dimness, aren't they still shimmering orbs of beauty in the vast cosmos? Just remember, every star has its own brilliance and charm.
Red dwarfs have average surface temperatures ranging from about 2,400 to 3,700 degrees Celsius (4,352 to 6,692 degrees Fahrenheit). They are cooler and dimmer than our Sun, which has an average surface temperature of about 5,500 degrees Celsius (9,932 degrees Fahrenheit).
Yes, all those types of stars have left the main sequence.

White Dwarfs, Supergiants, and Red Giants are stars that are found in the sky.

No, white dwarfs are much hotter than giants. Giants are stars in the later stages of their evolution, while white dwarfs are the remnants of dead stars that have exhausted their nuclear fuel. White dwarfs can have surface temperatures in the tens of thousands of degrees Kelvin, while giants have lower surface temperatures.
The size of the sun is considered average compared to other stars. There are much larger stars, known as supergiants, and smaller stars, known as dwarfs, in the universe.
Red dwarfs have average surface temperatures ranging from about 2,400 to 3,700 degrees Celsius (4,352 to 6,692 degrees Fahrenheit). They are cooler and dimmer than our Sun, which has an average surface temperature of about 5,500 degrees Celsius (9,932 degrees Fahrenheit).
Dwarfs, such as white dwarfs or brown dwarfs, are small in size but can still be very bright because they have high temperatures that produce intense luminosity. The brightness of a dwarf is determined by its surface temperature, not its physical size. Therefore, even though dwarfs are smaller than the sun, their high temperatures allow them to emit significant amounts of light.
The average temperature for a white dwarf star is around 10,000 to 100,000 Kelvin, which is significantly cooler than other types of stars. Despite their high temperatures, white dwarfs are considered "dead" stars as they no longer undergo nuclear fusion reactions in their cores.
White dwarfs have a broad spectrum, ranging from ultraviolet to near-infrared. However, they are most prominent in the blue and ultraviolet part of the spectrum, due to their high surface temperatures.

Some of the coolest stars in the Universe are known as red dwarfs, which have temperatures around 3,000 Kelvin. These stars are small and faint compared to other types of stars, but they are the most common type in the Milky Way. Despite their cool temperatures, red dwarfs can have extremely long lifespans.
