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.
What is hotter 23 degrees celsius or 65 degrees Fahrenheit?
23 degrees C is hotter because it equals 73.4F
Does an oven get hotter than the sun?
No. A home oven cannot get hotter than about 500 degrees F, while the surface of the Sun is over 10,000.
How do white dwarfs compare to super giants in terms of temperature and luminousity?
White dwarfs are typically much hotter than super giants, with surface temperatures ranging from about 5,000 to over 100,000 Kelvin, while super giants have surface temperatures between 3,500 and 20,000 Kelvin. However, despite their higher temperatures, white dwarfs are far less luminous than super giants, which can be thousands to millions of times more luminous than the Sun due to their massive sizes and energy output. In summary, white dwarfs are hotter but less luminous compared to super giants.
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?
Because luminosity is a measure of brightness over distance. Also white dwarfs are a hundred times smaller than the Sun. Most white dwarfs are a long way away and thus are difficult to see.
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?
I think white dwarfs. This is because they are much more low mass than black holes. White dwarfs are much more common in the universe than black holes, because we have only discovered a few black holes whereas we are aware of many white dwarfs.
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. Blue giants(or hypergiants) are hotter than Red giant stars. White dwarves are also hotter but they are smaller than blue giants. (As is implied by the name.)
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
