Why aren't there any green stars?

Answer 1

well I'm not too sure but there is a possibility of green stars existing but we just see them as more yellow due to gravitational red shifting.hopefully u know how to work out equations on gravitational red shifting.if u do then all u have to do is take a star of M>mass of the sun but less than the Chandrasekhar limit and having a wavelength of 500nm(frequency of 6*10^-14Hz) and hence calculate the original frequency.

Answer 2

What do you mean blue/green/brown/black being cooler than red? Blue is emitted by objects glowing hotter than objects that emit white light (hottest color of your hot). Brown then black are right consecutively, but not green. Wish that brown exists on the spectrum between red and infrared (infrabrown would instead be called)! Even though brown don't exist on the spectrum, brown stars in essence do exist.

Answer 3

there aren't any green stars because the light we see from the star is yellow not green. But all light are the color of the rainbow. so there are green star but are eyes don't allow us to see green from the star but yellow.

Answer 4

A star's colour indicates its surface temperature from blue (very hot) through white, yellow, orange, red, and brown (very cool).

A couple of answerers got this reversed: blue really is hotter than red. Think about a poker heating in a fire. It starts out glowing red, then orange, then white (white hot), and, if heated enough, would glow blue. Green just isn't part of this continuum.

Answer 5

Colors emitted by stars indicate their temperatures. Since stars are in fact burning planets (with plenty of explosions happening on their surfaces), they have very high temperatures. However, the color green is associated with fires of lower temperatures while colors like white, yellow, orange and red are associated with fires of high temperatures. Consequently, it's not likely to have a green star. :)

Answer 6

celebrity colours oftentimes come from a phenomena stated as "black physique radiation" and are suitable to warmth. as a results of fact the temperature gets greater the colour is going from pink to orange, yellow and then white. an extremely heat celebrity is a bluish white. You get the comparable bring about the international with the aid of heating some thing like steel to three of thousand ranges.

Answer 7

Hey Dude....Nice to Meet You:

In general,
White, Yellow, Orange, and Red are indicative of high heat
(highest to lowest of those shown).

Blue, Green, Brown and Black are indicative of lower heat levels, even absence of major heat supplies (highest to lowest of those shown).

Stars are vast nuclear fusion factories where enormous amounts of hydrogen gas is being converted into helium gas via nuclear fusion. The fusion has been created by the intense pressure and heat from the weight/mass of all of that gas pressing down on the central core of the star.

A star which was bluish, greenish, brown, or black would have had its nuclear fusion reactions reduced down to minimum levels or extinguished.

The fusion process is what gives of energy in the form of heat and radiation (Full Spectrum of Light, X Rays, Gamma Rays). So, as the fusion process dwindles down, the emitted light would behave the same, and recognition/observation of the star from great distances would become virtually impossible except possibly via radio emissions reception techniques using large, steerable antenna arrays.

Think of it like this: "White/Yellow/Orange/Red = Hot."
and "Blue/Green/Brown/Black = Cool." If you study a flame, that is quite similar to what you will find.

Finally, when you observe a Star, what you are seeing is the light radiation from it. Planets do not emit radiation. They do reflect light from their central solar object (star, or our star - the Sun). Seen from great distances, however, the reflected light from various planets circling distant stars is "scattered" and not direct radiation coming straight from the solar object, and thus of lesser intensity. So, when we look at a distant star (4 Light Years or Hundreds of Light Years away) the direct radiation from that star is what we see, and that direct radiation is so intense that it blinds us preventing recognition of other smaller objects in the nearby vicinity such as that star's planets and their moons. Look into a car's headlights at night and you will be unable to see anything in the near vicinity of the car - just the bright headlights and blackness around them.
