Highly luminous stars tend to be massive and are often situated in the upper regions of the Hertzsprung-Russell diagram, typically in the blue supergiant or red supergiant categories. They have high temperatures and emit large amounts of energy, resulting in their brightness. These stars often have short lifespans, burning through their nuclear fuel rapidly compared to less luminous stars. Examples include stars like Betelgeuse and Rigel.
What else can I help you with?
Are stars luminescent?
Strictly speaking, no; stars are incandescent (light resulting from heat) as opposed to luminscent (light resulting from non-thermal based effects). One might, however, safely describe stars as "luminous" in a metaporical sense.
What is an irregular luminous band of stars called?
An irregular luminous band of stars is called a "galaxy." Galaxies are massive systems of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity. They come in various shapes and sizes and can contain billions to trillions of stars.
What sequence of stars is listed in order of increasing luminosity?
The sequence of stars listed in order of increasing luminosity typically includes red dwarfs, main-sequence stars (like our Sun), giant stars, and supergiant stars. Red dwarfs are the least luminous, followed by main-sequence stars, then giant stars, and finally supergiants, which are the most luminous. This order reflects the increasing energy output and size of the stars as they evolve.
What is the least luminous spectral class?
Spectral class Y, which is typical of "brown dwarf" stars.
How can a non luminous body be made luminous Give an example?
Luminous objects create light .A non luminous object does not give off light.For instance, my feet are not luminous.Our sun and the rest of the stars in the universe are luminousNon-luminous objects are the ones who doesn't have its own light like you can say moon,trees, branches,plants, metals mirrors bricks etc.
What is the Collective noun for an irregular luminous band of stars?
An irregular luminous band of stars is called a galaxyof stars.
Are the stars and moon luminous?
Stars are luminous, shine by themseves. Moon isn't, it can only reflect light.
Are blue stars more luminous?
Blue stars are more luminous than other main sequence stars but not necessarily brighter than giant and supergiant stars.
What color are very heavy stars?
Generally, the more massive a star is, the more luminous they are. The most luminous stars appear blue.
Are stars luminescent?

Stars are brilliant balls of gases that are?
luminous
Are stars luminous or non luminous?
All things, except black holes, are luminous. That includes stars. You might think that some other things are not luminous but that's because you can't see the kinds of light that they emit.
Are all nebulae luminous?
Technically, no nebulae are luminous. The ones that appear as such have stars either within or near them, and the nebulae merely reflect the light emitted by these stars.
A name for a luminous object?
sun, stars, CD,
What are the stars?
A star is a massive, luminous ball of plasma.
What is the most luminous object discovered in space?
stars
Is a star Betelgeuse luminous?
There's only one star that we call 'Betelgeuse', and that one is very highly luminous.
