There are a lot of these. They are mainly the "Red Giant" and "Red Supergiant" stars.

Are stars cooler than the sun brighter or dimmer?
a sun is a star so it would be considered both dimmer .
What makes some stars appear brighter than others the temperature or the size?
It is a mixture of both. A hotter star will generally appear brighter than a cooler star of the same size. Similarly, a large star will appear brighter than a small one of the same temperature. The brightest stars are generally red supergiants, which are comparatively cool stars, but are so large that their size more than makes up for it. A star's apparent brightness from any given vantage point also depends on its distance. The closer a star is to you, the brighter it will appear.
Why can one star be more brighter than another?
They are larger and have more energy
Which is the brighter star aldeberan or Betelgeuse?
Betelgeuse is more luminous than Aldebaran.
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.
Which star is cooler and many times brighter than Earth's Sun?
The Sextopia star
How does the HR diagram explain why some smaller cooler stars are brighter than larger hotter stars?
In terms of absolute magnitude, a larger hotter star will necessarily be more luminous than a smaller cooler star. However, if a smaller cooler star is much closer to us than a larger hotter star, it may appear to be brighter. None of this has anything to do with the HR diagram.

What is a brighter star?
A star that is brighter than another.

How do star are more brighter than other stars?
Stars are more brighter than other stars because they have different characteristics that affect their luminosity. Luminosity is the amount of energy that a star emits per unit of time. It depends on the star's size, temperature, and distance from the observer. Some of the factors that make stars more brighter than other stars are: Size: Larger stars have more surface area and can emit more light than smaller stars. Temperature: Hotter stars have higher energy and can emit more light than cooler stars. Distance: Closer stars appear brighter than farther stars because their light has less space to travel and lose intensity.
Which is the brighter star aldeberan or Betelgeuse?
Betelgeuse is more luminous than Aldebaran.
Star A is a first magnitude star. Star B is a sixth magnitude star. Which star is brighter and by how much?
A magnitude 1 star is 100 times brighter than a magnitude 6 star.A magnitude 1 star is 100 times brighter than a magnitude 6 star.A magnitude 1 star is 100 times brighter than a magnitude 6 star.A magnitude 1 star is 100 times brighter than a magnitude 6 star.
Why does Sirius star look brighter than alpha centauri star?
Because it actuall IS brighter.
How can you tell if a star is brighter than another?
The star might be closer to the Earth, or it is just brighter than the others. :D
