What else can I help you with?
Are blue stars more luminous?
Blue stars are more luminous than other main sequence stars but not necessarily brighter than giant and supergiant stars.
Why are old stars more luminous than young stars?
Well, it depends on if it's positioned closer to the earth or if they are about to supernova. And since the sun is the ONLY star in our solar system that would be the most luminous. =) hoped that helped.
What are different sizes or stars?
Stars can be classified into different sizes based on their mass and luminosity. The most common sizes are dwarf stars (like our Sun), giant stars (larger and more luminous than the Sun), and supergiant stars (the largest and most luminous stars, like Betelgeuse and Rigel). There are also intermediate sizes like subgiant stars.
How luminous is a white dwarf?
White dwarfs are not very luminous compared to other stars. While they can be thousands of times more luminous than the Sun due to their high surface temperatures, their small size limits their overall brightness. They are often dimmer than main sequence stars of similar mass.
What 2 types of stars can form from a nebula?
Two types of stars that can form from a nebula are main sequence stars, like our sun, and giant stars, which are larger and more luminous than main sequence stars.
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 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.

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.
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.

How big are blue supergiants?
Blue supergiants are among the most massive and luminous stars in the Universe. They can be up to 20 times more massive than the Sun and have radii several hundred times larger. These stars are relatively rare compared to other types of stars.
How do the blue star differ from the red star?
Blue stars are hotter, larger, and more luminous than red stars. They have shorter lifespans due to their high energy output. Red stars are cooler, smaller, and less luminous, and they have longer lifespans.
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.
Explain how a red star can be more luminous than a bluish-white star?
A red star can be more luminous than a bluish-white star if it is larger in size and/or hotter in temperature. The luminosity of a star is determined by its size and temperature, with larger and hotter stars emitting more energy. Therefore, a red star that is larger and hotter than a bluish-white star can be more luminous.
