Can you now explain why blue stars hotter than the red stars?

Well, to answer this, a shorter wavelength means greater energy. This is important because if you look at the spectrum, blue photons have more eery than red photons so the blue star generates more energy and more heat than the red. To answer simply, the red stars are lower in temperature than the blue stars.

Are blue stars colder?

Stars have different colors, which are indicators of temperature. The hottest stars tend to appear blue or blue-white, whereas the coolest stars are red.

Why are blue stars hotter than yellow?

The surface temperature of a star determines the color of light it emits. Blue stars are hotter than yellow stars, which are hotter than red stars. Remember that magnitudes decrease with increasing brightness, so if B – V is small, the star is bluer (and hotter) than if B – V is large.

Is a blue star hotter than a yellow star?

Red stars are the coolest. Yellow stars are hotter than red stars. White stars are hotter than red and yellow. Blue stars are the hottest stars of all.

Is blue hotter than red?

Why are hot things colored? (incandescence) In the English language, we understand “white hot” to be hotter than “red hot,” while “blue” is usually associated with degrees of coldness, as in “cool blue” or “icy blue.” In terms of real temperature, “blue hot” is hotter than “red hot.”

Why are yellow stars hotter than red stars?

Why are hot stars blue and not red?

The color of a star is linked to its surface temperature. The hotter the star, the shorter the wavelength of light it will emit. The hottest ones are blue or blue-white, which are shorter wavelengths of light. Cooler ones are red or red-brown, which are longer wavelengths.

Is blue hotter than yellow?

The surface temperature of a star determines the color of light it emits. Blue stars are hotter than yellow stars, which are hotter than red stars.

Is yellow warmer than red?

A dividing line splits the wheel into warm and cool. The line location varies based upon the reasoning of the theorist. Regardless, the general idea is the warm colors are Red, Orange and Yellow; and the cool colors are Green, Blue and Magenta (Figure 2).

Why are blue stars hotter than yellow stars?

Why blue star is the hottest?

The surface temperature of Eta Carinae is 40,000 Kelvin, and it shines with much of its radiation in the ultraviolet spectrum. So, remember, blue stars are blue because of the temperature of their surface. And they’re so hot because blue stars are much more massive than cooler stars like our Sun.

Why are blue stars hotter than red?

Blue stars are hotter. This is the same principle as objects you’re more familiar with. When you heat up a piece of metal hot enough, it starts glowing red. As it gets hotter, it becomes more orange, yellow, and then white (like a lightbulb, which is so hot it emits white light). This is the same case with stars.

What color of light does the hottest star emit?

Just look at the electromagnetic spectrum. You will see that blue has the highest energy in the visible spectrum, then comes yellow, and lowest comes red. Lower wavelength means higher energy. Now the stars that emit the most energy (aka hottest) would obviously emit light with highest energy, which is blue.

What is the color of the stars?

This makes the cooler stars appear red and the stars with the higher temperatures appear blue or white. From cool to hot, the colors can appear red, orange, yellow, green and blue. If you remember the colors of the rainbow, you will see that these are in the same order. There is another important factor that can alter a stars color.

What is the difference between a blue and yellow star?

Blue stars are the most massive stars and the greater pressure on their cores make the fusion go much faster, generating a great amount of heat that makes the star hotter. Yellow stars like the Sun have less mass than the blue stars so the pressure on their core is less and the fusion is going slower.
