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.

How can dwarfs be so bright when they are smaller than the sun?
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.
Which is hotter 20C or 20F?
20°C is hotter than 20°F. 20°C is equivalent to 68°F.
What is hotter 10 degrees Celsius or 20 degrees Celsius?
20 degrees Celsius is hotter than 10 degrees Celsius.
Which is hotter 30C or 30F?
30 degrees Celsius is hotter than 30 degrees Fahrenheit. 30C is equivalent to 86F, so it is warmer by 56 degrees.
What is hotter 23 degrees celsius or 65 degrees Fahrenheit?
65 degrees Fahrenheit is hotter than 23 degrees Celsius.
How is it possible for white dwarfs of have a lower luminosity than the sun even though the sun is much cooler than the white dwarfs?
White dwarfs have lower luminosity than the Sun because they are much smaller and have a smaller surface area radiating heat. Despite being hotter than the Sun, the small size of white dwarfs results in lower total energy output. This makes them appear dimmer than the Sun.
Which is hotter red stars or whitish - blue stars?
White Dwarves and Blue giants are both hotter than Red giant stars.
Is the surface temperature of white dwarfs higher or lower than red super giants?
Yes dwarf has higher temperature
Are there more white dwarfs of more black holes?
There are more white dwarfs than black holes in the universe. White dwarfs are the end stage of low to medium mass stars, while black holes are formed from the remnants of massive stars. Since low to medium mass stars are more common than massive stars, there are more white dwarfs in the universe.
What is the opposite dwarfs?
The opposite of dwarfs is giants. Giants are typically depicted as larger-than-life beings, often towering over others in size and strength.
True or false Red stars are hotter than whittish- blue stars?
False. Red stars are cooler than whiteish-blue stars. The color of a star is an indication of its temperature, with red stars being cooler and white-blue stars being hotter.
How do white dwarfs compare with super-giants in terms of temperature and luminosity?
The plural of dwarf is "dwarves". White dwarves are hotter than supergiants. White dwarves also have much less luminosity. This is related to their very small surface area. Since white dwarves no longer produce energy, they will cool down over time - but this takes quite a while.
Are white dwarfs older than the sun?
Some white dwarfs are older than the sun, and some are not. More massive red dwarfs form from stars larger than the sun, which do not last as long.
Are there white dwarfs past Pluto?
Yes. All white dwarfs are orders of magnitude farther away than Pluto is.
What is a clue to a stars temperature?
Its colour. White stars are hotter than blue stars which are hotter than yellow which are hotter than orange, which are hotter than red.
Are main sequence stars older than white dwarfs?
no
What is hotter than white hot?
White hot is the hottest temperature that a material can reach before it starts to emit visible light. Temperature-wise, blue flame or blue-white flame is hotter than white hot.
