They would have different sizes, but all much larger than our Sun, being hundreds of times larger. If some of them were where our Sun is now, we would be inside the star because they would reach out beyond where we are in relation to our Sun.

The absolute magnitude of a star is it's magnitude at a standard distance (rather than it's actual distance from earth).

Which stars always have large positive absolute magnitude?
Does it mean that the star is a main sequesnce star? ( . Y . ) The above isn't true. A star can be a blue supergiant and be on the main sequence but still not be even visible to us, therefore the apparent and absolute magnitude wouldn't be the same. But to answer your question, I don't think it has a name, it just means that you are seeing the star's absolute and apparent magnitude at the same time, so if you placed the star at 32.6 light years away(the absolute magnitude scale)then the star would not appear to change in brightness
Is sun the brightest star?
The brightness of a star is usually referred to as its magnitude. Every star has two magnitudes. The apparent magnitude is how bright it appears to us here on earth. The absolute magnitude is the apparent magnitude that the star would have, if it were viewed from a standard distance. The apparent magnitude of our sun is vastly greater than that of any other celestial object. In terms of absolute magnitude, our sun can't begin to compare with some of the big bright stars in the universe.
What kind of graph graph that shows the relationship of a star's temperature to its absolute magnitude?
That is called the HR diagram (Hertzsprung Russell) and the temperature is along the horizontal axis while the vertical axis is the star's absolute magnitude. Each star has a fixed point in this diagram, and it shows that most stars belong in a broad band on the left called the Main Sequence.
What star is the greatest luminosity or absolute magnitude?
That isn't know with certainty. You can see a list in Wikipedia, if you search for "List of most luminous stars"; the article describes some of the caveats, for example, the distance to the stars are not always known with great precision. Also, this obviously only includes known stars, which are relatively close to us (mainly in our own galaxy).
Compare and contrast the sun with other stars on the hr diagram?
The sun is closer to Earth than any of the other stars. Light from the sun takes 8 minutes to reach Earth, but light from others stars take years to reach Earth. They both are giant balls of hot gas.
What is absolute magnitude of most yellow stars?
Most "yellow" stars fall into the classification of type G - the same as our Sun.They have an absolute magnitude of around 5.

Which magnitude gives the most information about the physical nature of a star?
absolute bolometric magnitude

Which star has the largest absolute magnitude?
There is a star in the Large Magellanic Cloud called R136a1 which has an absolute magnitude of -12.5. Undoubtedly others will turn up as time goes by. M33-013406.63 in the Traingulm Galaxy has an absolute magnitude of -12.2 to -12.7 (not quite sure of the exact M)

How does the sun compare to other stars in term of surface temperature apparent magnitude absolute magnitude and size?
The Sun is approximately at the percentile 85 or 90, with respect to most size-related criteria (size, brightness). That means that about 85-90% of stars are smaller and less bright than our Sun. The exact number is hard to establish, since it has turned out difficult to have good estimates about the number of red dwarves.

What body in space is the most luminous star?
The most luminous star in space is named R136a1 which is 160,000 light years away from space. It measures absolute bolometric magnitude of -12.6 , and an apparent visible magnitude of 12.84.
Which stars are significant in Leo?
The three most significant stars in Leo the Lion are : Alpha Leonis or Regulus (the Lion's heart) with an apparent magnitude of 1.35, Beta Leonis or Denebola (the Lion's tail) with an apparent magnitude of 2.14 and Gamma Leonis or Algieba (where the Lion's mane meets his body) with an apparent magnitude of 1.98
What colour are the brightest stars?
white Each star type has it's own emission spectrum. There are stars that are very hot and look blueish to the eye (but have a lot of ultra violet if you have a sensor that can detect those wavelengths) and there are stars that look reddish because they are not as hot on the surface, they still can appear bright because they are so large and can be (relatively) close to us too.
