THE FATE OF MASSIVE STARS 1 These fairly low mass stars end as white dwarfs made of C and O.  M > 4 Msun: Hot enough to fuse C and O to heavier elements. Very massive stars (massive enough to qualify as supergiants) are able to fuse all the way to iron, the `end of the line' as far as fusion is concerned.

- The coolest stars are the red dwarfs/red giants, with surface temperatures of 3,500 Kelvin or less. As the surface temperature gets hotter, the color of the star turns orange, and then yellow-orange, and then yellow, yellow-white, and then around 5,800 Kelvin it appears white.

- Cooler still are the orange stars. The coolest stars appear red. That's how the spectrum of a star is related … to its surface temperature. The reason is that the hotter the star, the shorter the wavelength at which the light is most intense in its spectrum. Blue light is of shorter wavelength than red.ize and color are not directly related at all. The color of a star is instead related to it's temperature, with red (class M) stars being the coolest and blue stars (class O) … being the hottest. 2 people found this useful.

Stars great and small, and their life cycles These stars are highly visible in the sky, even when they are far from the earth. They burn brighter, but their lifetimes are correspondingly much shorter than those of less massive stars. Low-mass stars have a mass of between a tenth and a half of the sun.

Stars great and small, and their life cycles High-mass stars have a mass eight or more times that of our sun. They are a thousand to a million times more luminous than the sun, and around ten times bigger in diameter. These stars are highly visible in the sky, even when they are far from the earth.nce the nebula fades, the core is called a white dwarf, and has a temperature of 100,000 K. This cools slowly, over billions of years, to become a black dwarf too faint to detect. This is the end of the star’s life.

White dwarf A white dwarf is very hot when it is formed, but since it has no source of energy, it will gradually radiate away its energy and cool. This means that its radiation, which gives it a blue or white colour at the start, lessens over time.

- As we said last time, the spectral sequence O, B, A, F, G, K, M is a temperature sequence, with the hottest stars being of type O (surface temperatures 30,000-40,000 K), and the coolest stars being of type M (surface temperatures around 3,000 K).

- After years of cataloging stars, they were divided into 7 basic classes: O, B, A, F, G, K and M. Note that the spectra classes are also divisions of temperature such that O stars are hot, M stars are cool. Between the classes there were 10 subdivisions numbered 0 to 9. For example, our Sun is a G2 star. Sirius, a hot blue star, is type B3. Why do some stars have strong lines of hydrogen, others strong lines of calcium? The answer was not composition (all stars are 95% hydrogen) but rather surface temperature.

Stars Betelgeuse in Orion is an example of a red supergiant star. White Dwarfs-A white dwarf is the remnant of an average-sized star that has passed through the red giant stage of its life. After the star has used up its remaining fuel.

Lecture 13 Main Sequence blue giants such as Rigel are located on the left-hand side of the H-R diagram. The order is O B A F G K M, and these are spectral classes based on color and tem … perature. The hottest stars burn blue/white because blue light has the shortest wavelengths and the highest temperatures.

- 1 Different temperatures, or spectral types of stars group together on a plot of absolute magnitude versus temperature, called a Hetzsprung- Russell diagram.  Star types include main sequence stars, neutron stars, variable stars, dwarfs and white dwarfs, giants and super giants.

The largest star currently known She noted that the largest stars are the coolest. So even though Eta Carinae is the most luminous star we know of, it’s extremely hot – 25,000 Kelvin – and so only a mere 250 solar radii. The largest stars will be the cool supergiants. For example, VY Canis Majoris is only 3,500 Kelvin.

What is the Hottest Star? It’s surface temperature is a mere 11,000 Kelvin. Another star in Orion, Bellatrix, has a temperature of 21,500 Kelvin. That’s even hotter. But the hottest known stars in the Universe are the blue hypergiant stars. These are stars with more than 100 times the mass of the Sun. One of the best known examples is Eta Carinae, located about 7,500 light-years from the Sun.

Atom Well, not exactly. There are many different types of stars, from the tiny brown dwarfs to the red and blue supergiants. There are even more bizarre kinds of stars, like neutron stars and Wolf-Rayet stars. Let’s take a look at all the different types of stars there are.Red giant Betelgeuse.ed Dwarf Star. Red dwarf stars are the most common kind of stars in the Universe. These are main sequence stars but they have such low mass that they’re much cooler than stars like our Sun. They have another advantage.

Temperature of the Hottest Star Encyclopedia Britannica. 2000. Class O includes bluish white stars with surface temperatures typically of 25,000-50,000 K (although a few O-type stars with vastly greater temperatures have been described); lines of ionized helium appear in the spectra..

Black Dwarf Stars: The (Theoretical) End of Stellar Evolution View full size image. The last stage of stellar evolution is a black dwarf. Because they emit no heat or light, these objects would be a challenge to detect if they existed today. However, at less than 14 billion years old, the universe is still too young to have created any black dwarfs!

- A typical white dwarf has a carbon and oxygen mass similar to the Sun, but is much smaller in size (similar to the Earth). It is much hotter (25,000 K), but because of its small size its luminosity is low.

Red Dwarfs: The fascinating stars that live for trillions of years By far the most abundant type of star, however, is the red dwarf. Smaller than our Sun but with a much longer lifetime, these balls of burning gas are extremely important in our understanding of the cosmos. Red dwarf stars typically have a mass of between 7.5% and 40% of the Sun.

What is the hottest star? (solar system)? The hottest blue stars are about 40,000 degrees at the surface, and many millions at the core-much hotter than the sun, which is 16 million in the core. We measure star temp at the surface, however, so the sun is a relatively cool star at about 4500 degrees on the surface. The Sun is the only star in our solar system. Vega and Rigel are hot blue stars in the constellations Lyra and Orion. eri · 9 years ago.
