Are blue stars more luminous?
Blue stars are more luminous than other main sequence stars but not necessarily brighter than giant and supergiant stars.
Is the star Rigel luminous?
Very!! It is about 66,000 times more luminous than our Sun
The next stage of life for the sun in about 5 billion years is?
It will become a red giant. However, the Sun will gradually emit more and more energy before that, and it is believed that long before it turns into a red giant - in "only" 1/2 or 1 billion years - it will become too hot for life as we know it to survive on Earth.It will become a red giant.

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.
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.
Are blue stars more luminous?
Blue stars are more luminous than other main sequence stars but not necessarily brighter than giant and supergiant stars.
Explain how a red star can be more luminous than a bluish-white star?
By being far larger - a red giant/supergiant.
What is a bright giant?
A bright giant is a class of star that don't quite make it into the supergiant class but are much more luminous than giants.Eg. Epsilon Canis Majoris (Adhara): a blue-white (B-type) bright giant
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
Which star is more luminous R136a1 or VY Canis Majoris?
R136a1 is the most luminous at about 8,700,000 times more than the Sun. VY Canis Majoris is only 450,000 times more luminous than our Sun.

What color are very heavy stars?
Generally, the more massive a star is, the more luminous they are. The most luminous stars appear blue.

What is luminous flame and Explain why it takes a longer time to heat equal amount of water using a luminous flame?
yellow color in a luminous flame produces soot or carbon. carbon dioxide is present in the luminous flame but when its combined with oxygen the flame is nonluminous which is in a blue color. it takes a longer time because luminous flame is cooler than the nonluminous. I only know what luminous flame is. The inner part of luminous flame is blue while the outer part of the luminous flame is yellow. It is unsteady. Yeah. Carbon Dioxide is only present in the luminous flame. When oxygen is combined with the flame, the flame will become non- luminous which is inner and outer part are blue. Hmm. Actually luminous flame's hottest part is at the bottom while non- luminous flame hottest part is at the middle and the top. That's all i know. If i know more, i will update for you. Thank you!

Why is Neptune the densest gas giant?
We're not certain. It may be that since Neptune is the farthest gas giant from the Sun, and cold gasses become more dense.
What are larger and more luminous than red giants?
Supergiants are bigger and more luminous than the red giants. Supergiants are stars that have a mass that is eight times more than the sun.
