WebbAt the top end of the main sequence, the stars are large, hot, and very luminous. Because of their size and color, they are referred to as blue giants. The very largest are called blue supergiants. At the other end, stars are small, cool, and faint. They are known as red dwarfs. Our Sun lies right in the middle. Webb11 juni 2024 · Red dwarf stars include the smallest of stars, weighing only 7.5% to 50% of our Sun’s mass. Since they are small, they burn at a lower temperature, reaching around 6,380 degrees Fahrenheit / 3,500 degrees Celsius. Since they have low temperatures, red dwarf stars are much dimmer than our Sun.

WebbInstead, we see that the stars cluster into certain parts of the H–R diagram. The great majority are aligned along a narrow sequence running from the upper left (hot, highly luminous) to the lower right (cool, less luminous).

http://abyss.uoregon.edu/~js/glossary/star.html WebbOn the modern magnitude scale, Sirius, the star with the brightest apparent magnitude, has been assigned a magnitude of −1.5. Other objects in the sky can appear even brighter. Venus at its brightest is of magnitude −4.4, while the Sun has a magnitude of −26.8.

WebbIts temperature is a cool 3548 K (the Sun is about 5770 K), while its luminosity is about 50,000 times brighter than the Sun. This must mean that it has a very large radius, in fact about 600 times larger than the solar radius! Similarly, stars that are very hot and yet still dim must have small surface areas.

WebbSince the stars at the upper right are very luminous yet nonetheless have cool, reddish surfaces, astronomers call them red giants. Similarly, since the stars at the lower left are very dim yet also white-hot, they are called white dwarfs. We have met the white dwarfs already, in a theoretical way. Now let's see where the real ones come from. overhead solutions.comWebbBecause of its low luminosity, a red dwarf’s habitable zone (the region near a star where liquid water could be found on a planet’s surface) is very close to the star.
