What range of the H-R diagram is your Sun placed in because its temperature and absolute magnitude are average?
between the yellow stage color on the digram
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
Why does Arcturus star have greater absolute magnitude than the sun buy a much lower apparent magnitude?
The apparent magnitude is how bright the star appears to us, but stars are all at different distances so that a star that is really bright might look dim because it is very far away. So the absolute magnitude measures how bright the star would look if it was placed at a standard distance of 10 parsecs. When the absolute magnitude is greater than the apparent magnitude, it just means that it is closer than 10 pc. The brightest stars have absolute magnitudes around -7.
Why does a star such as Betelgeuse which is located far from earth have much greater absolute magnitude than apparent magnitude?
well my reason is that the betelgeuse must be very large , because they said that the betelgeuse is located far from earth .

How are absolute magnitude and apparent magnitude alike?
Absolute magnitude and apparent magnitude are the same because they are both ways on how to measure the brightness of a star. Absolute magnitude is how bright is the star if we will see it in a 32.616 light-years distance while apparent magnitude is the brightness of it that we see on Earth.

What is the absolute magnitude for a black hole?
"Absolute magnitude" talks about the intensity of light radiating from a source. The black hole is black because no light radiates from it. So you'd have to say that its magnitude ... visual, absolute, intrinsic, or any other kind of magnitude ... is infinite. (Magnitude numbers are higher for dimmer sources.)
Why is the absolute magnitude of some stars greatar than their apparent magnitude?
The question is: Why is the apparent magnitude of some stars less than their absolute magnitude. Or: Why do some stars not look as bright as they really are ? The answer is: Because they're so far away from us.
Does the sun seem brighter than other stars because of the absolute magnitude?
No because of its proximity to the earth.
Why is the absolute magnitude of some stars greater their apparent magnitude?
The apparent magnitude is how bright the star appears to us, but stars are all at different distances so that a star that is really bright might look dim because it is very far away. So the absolute magnitude measures how bright the star would look if it was placed at a standard distance of 10 parsecs. When the absolute magnitude is greater than the apparent magnitude, it just means that it is closer than 10 pc. The brightest stars have absolute magnitudes around -7.
Is it possible for two regular stars to have the same absolute magnitude but differ in apparent magnitude?
One dimmer star can be closer than a brighter star that is far away. Light flux decreases as the square of the distance. A star that is three times as far away will have to shine nine times brighter than the closer star (absolute magnitude) to appear to have the same magnitude (apparent magnitude). Because apparent magnitude is the brightness of a star, as seen from Earth, whereas absolute magnitude is the brightness of a star as seen from the same distance - about 32.6 light years away.
Why is absolute magnitude of some stars greater than their apparent magnitude for stars?
The apparent magnitude is what we see, and this can be measured directly. The absolute magnitude must be calculated, mainly on the basis of (1) the apparent magnitude, and (2) the star's distance. So, to calculate the absolute magnitude, you must first know the star's distance.
What happens to the absolute magnitude of a star as one moves up the vertical axis?
The absolute magnitude is referred to a constant, standard distance, so it doesn't change. But the apparent visual brightness increases (magnitude number decreases), because as you climb the vertical axis, you obviously move closer to the star.
Could you round off temperature data?
No because it is an absolute value
The impossibility of reaching a temperature of absolute zero is incorporated in?
The Third Law of Thermodynamics."Absolute zero (0 K) is the lower limit of temperature. The temperature of absolute zero cannot be attained physically because to do so would require virtually all the heat to be taken from an object. Therefore, it is impossible to attain a temperature of absolute zero."
