Yes, stars are luminous.
Stars emit energy in the form of light. The immense temperature and pressure inside stars fuses atoms together in a process called nuclear fusion. This releases energy, largely in the form of light and heat. Some stars shine more brightly than others and this brightness is known as the star's magnitude. There are two types of magnitude.
1. Apparent magnitude - This is a measure of how bright the Star appears to us (this does not take into account how far away from us the star is).
2. Absolute magnitude - A measure of how bright the star actually is once we allow for distance (if it is further away it will appear to be less bright to us but this scale compensates for this).

Is a lamp luminous or non luminous?
Planets( Mercury, Venus, Earth, Jupiter, Saturn, Uranus, Neptune) and also Moons are Non-Luminous objects they don't emit light. The reason we see them because they reflect light from the Sun.
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.
When a lamp is turned off is it luminous or non-luminous?
If the bulb is switched off, then we would call it non-luminous.
What are luminos body?
Bodies which emit light are luminous bodies and those who don't emit light are known as non luminous bodies Example - stars are luminous bodies while planets are non luminous bodies Tube light is a luminous body while a chair is non luminous
Is gold non luminous object?
sun (a luminous object) emits its own light and the moon ( a non luminous object ) reflects the light from the sun to earth that's how we can see the moon. The same way gold is a non luminous object.
The star have light?
because the star is luminous.
Is a star Betelgeuse luminous?
There's only one star that we call 'Betelgeuse', and that one is very highly luminous.
How can a cool star be more luminous than a hot star?
Luminosity is related to temperature and distance.A cool and thus less luminous star would be brighter than a more luminous star at a greater distance.Our Sun is a relatively cool star in comparison to say Rigel, but because it is closer it appears more luminous and brighter.
Would the sun be more luminous if it were hotter?
Yes luminous actually for a star to get hotter.
Is the star Rigel luminous?
Very!! It is about 66,000 times more luminous than our Sun
How is a star different to a planet?
'cause the star is self luminous and the planet is not .
What is a star in space?
A star is a luminous globe of hot gas that makes energy.
Why does the expansion of a star's envelope make it cooler and more luminous?
The star's expansion is caused by an increase in energy. Therefore, the star becomes more luminous and cooler due to production of more energy.
What are the stars?
A star is a massive, luminous ball of plasma.
Which star in the constellation Gemini is the most luminous?
Pollux
What is a hot self-luminous shpere of gas?
star
What is the most powerful star in the universe?
Depends on how you define power. If we take it as transferring energy then it will have to be the most luminous. So the most luminous star known in the Universe is R136a1
