Ask Us The color of a star determines the heat of the star. For example; a white dwarf star does not produce nearly as much heat as our sun does. However, one day, our sun will turn … into a white dwarf star. When this happens there will not be enough heat to live on Earth. 5 people found this useful.

Different Types of Stars in the Universe Stars are often classified according to spectral type. Although they emit all colors of light, spectral classification considers only the peak of this emission as an indicator of the star's surface temperature. Using this system, blue stars are the hottest, and are called O-type. The coolest stars are red and are called M-type. In order of increasing temperature, the spectral classes are M (red), K (orange), G (yellow), F (yellow-white), A (white), B (blue-white), O (blue). This bland categorization is often abandoned for a more descriptive alternative. As the coolest stars (red) are invariably the smallest, they are called red dwarfs. Conversely, the hottest stars are often called blue giants. There are a number of physical characteristics that vary for each of the different types of star.

The Life of a Star The colour of a star is determined by its temperature, the hottest stars are blue and the coolest stars are red. The Sun has a surface temperature of 5,500 degrees Celcius, its colour appears yellow. The energy produced by the star is by nuclear fusion in the stars core.

- The majority of stars emit most of their electromagnetic energy as visible light, the tiny portion of the spectrum to which our eyes are sensitive. Because wavelength correlates with energy, the color of a star tells us how hot it is: red stars are coolest, blue are hottest.he majority of stars emit most of their electromagnetic energy as visible light, the tiny portion of the spectrum to which our eyes are sensitive.

Stars A star's brightness is known as its magnitude. Astronomers rate the magnitude of a star with a scale that gives brighter stars a low number and dim stars a higher number. Each whole number on this scale is 2.5 times dimmer than the previous number. The brightest star the night sky is Sirius. With a magnitude of -1.46, it is almost 15 times brighter than a star with a magnitude of zero. Stars with a magnitude of 8 or more are too dim to see with the naked eye. Stars are identified by their color, which indicates their temperature.

- 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.

Star Colors and Luminosities: The H-R Diagram Emission nebulae are usually red, because hydrogen, the most common gas in the universe, most commonly emits red light. Reflection nebulae are clouds of dust that simply reflect the light of a nearby star or stars. Reflection nebulae are usually blue, because blue light scatters more easily.

What determines the color of a star other than temperature? The color of a star is basically decided by the surface temperature of the star. Any electromagnetic radiation is generated when an atom comes from excited state to lower energy state. The excitation of atom depends on the temperature; the atom will be excited to higher energy state when the temperature is higher.

Single, Double and Triple Pane Windows Explained Say you pay a truckload for some triple pane windows (which, by the way, run about 25 to 30 percent more than double panes), but the frame starts to leak or warp and the glass begins to fog. These are good signs that you spent a lot of money for a cheap product that was installed improperly.

Light from Stars A Star with a peak wavelength of 4000 Angstroms. Because stars emit light with different wavelengths, they have different colors. Stars do not just emit one wavelength of electromagnetic radiation, but a range of wavelengths. If you look at the amount of light a star gives off at different wavelengths, you would get a graph like the one shown to the right. The wavelength at which a star emits the most light is called the star's peak wavelength. The diagram on the right shows that this star has a peak wavelength of 4000 Angstroms. Question 2.

The Colour of Stars If you look up into the night sky you may be able to see a few thousand stars from a dark site. As the stars are all so distant they appear as points in the sky. Most appear white but a few stars such as Antares and Betelgeuse have an orange or reddish hue to them. Others such as Rigel suggest a bluer colour. The colours of stars, however, are not obvious in most stars for several reasons discussed below. Colour is nonetheless an important and useful property of stars.

What determines the color of a star? To put it basically, the lighter and bluer (except dark blue stars are normally hotter then light blue ones) a star is the hotter it is, and the redder and darker it is the cooler it is. Newer stars are normally hotter because they just began a cycle of burning up their vast supplys of fuel.

The Ten Brightest Stars In The Sky The word procyon is Greek for before the dog, for in the northern hemisphere, Procyon announces the rise of Sirius, the Dog Star. Procyon is a yellow-white, main-sequence star, twice the size and seven times as luminous as the Sun. Like Alpha Centauri, it appears so bright because at 11.4 light-years, it is relatively close. Procyon is an example of a main sequence subgiant star, one that

- View full size image. Sirius, also known as the Dog Star or Sirius A, is the brightest star in Earth's night sky. The name means glowing in Greek. With a visual magnitude of -1.46, the star is outshone only by several planets as well as the International Space Station. Because Sirius is so bright, it was well-known to the ancients. What came as a surprise to astronomers was the discovery of a companion star, Sirius B, in 1862.

Capella Is the brightest star in Auriga and the sixth brightest star in the sky, not including the Sun.he 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.
