It is much larger and has a greater surface area than the Sun, so each unit of area can be cooler and less luminous than an equal area on the Sun.

Is Arcturus bigger than the sun?
Arcturus
Is the star Rigel luminous?
Very!! It is about 66,000 times more luminous than our Sun
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 super is a star that is millions of times brighter than the sun?
Brightness is defined as the luminousity as seen from Earth. So the brightest star is the Sun.HD 93129A is a blue supergiant and one of the most luminous stars in the Milky Way and is 5,500,000 times more luminous than the Sun.
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.

Arcturus is a bit brighter than Vega, actually.

What are the advantages of using a non-luminous flame?
Non- Luminous can burn efficiently because luminous flames don't burn as efficiently as non-luminous ones, they don't produce as much energy. This means that the non-luminous flames have a lot more energy than luminous ones, and their flames are actually hotter. This is why the luminous ones look yellow and the non-luminous ones look blue. Hotter flames burn blue and (relatively) cooler ones burn yellow.
Which star is more luminous R136a1 or VY Canis Majoris?

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 blue stars more luminous?

What stage is Arcturus in?
Arcturus is in the latter part of a stars life. It is a red giant and it's mass is too low for it to "go" supernova. More than likely it's demise will be similar to our own Sun.
