If the Star's size is bigger, then the magnitude will also be larger. The magnitude is the brightness of a star. If the stars magnitude is greater, the size will be greater too.
A larger surface area (due to a larger mass) will emit more energy (a greater absolute magnitude).
Note however that there are very massive but small objects (neutron stars, black holes, etc.) that even though they have a great mass have small absolute magnitude (or are even invisible - or almost invisible).
What else can I help you with?
What is difference in a star's apparent magnitude and absolute magnitude caused by?
How far away the star is.
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.
What is the absolute magnitude of this star m equals 6?
Magnitude = m - 5 (log10D) - 1) Where D is the star's luminosity distance in parsecs ----------------------------------------------------------------- In order to calculate a star's absolute magnitude, we need two pieces of information: -- its apparent magnitude, i.e., how bright it appears from Earth, and -- its distance from us.
Explain why size is the only factor that determines the stars absolute magnitude?
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
How will a star bright if it was near the sun?
A star near the Sun might be brighter or dimmer, it depends on how big it is. Each star has an absolute magnitude and if you find out a star's absolute magnitude, and then subtract 31.4, that would be its visual magnitude at the Sun's distance from us.
What is the absolute magnitude of Altiar?
The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.
How bright a star actually is at a distance of 32.6 light years away from earth is?
That's the number called the star's "Absolute Magnitude".That is called the star's "absolute magnitude".
Is the brightness of a star compared to other stars called its magnitude.?
No; the "magnitude" is how bright the star is. It can either mean:* The apparent magnitude = how bright it seems to us, * The absolute magnitude = how bright the star really is (i.e., how bright it would seem at a standard distance).
How does the apparent-magnituede of a star differ from it absolute magnitude?
Absolute magnitude is how bright a star is. Apparent magnitude is how bright it looks to us (on Earth).
A star might be much brighter than it appears to be. This is called the star's absolute magnitude. The difference in apparent magnitude and absolute magnitude is due primarily to the star's -?
Distance
What distance is the absolute magnitude and the apparent magnitude of a star would be equal if the star is seen at?
The standard distance is 10 parsecs. At this distance the star's apparent magnitude equals its absolute magnitude. A star 100 parsecs away has an absolute magnitude 5 magnitudes brighter than its apparent magnitude. 1 parsec is 3.26 light-years.
What is difference in a star's apparent magnitude and absolute magnitude caused by?
How far away the star is.
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.
How bright a star actually is a distance of 32.6 light years from earth is called?
That's called the star's absolute magnitude.
Does the absolute magnitude of the sun show that it is the brightest star?
No. The sun has an absolute magnitude of 4.83. By comparison, Betelgeuse has an absolute magnitude of -5.85. Lower numbers indicate a brighter star. In this case Betelgeuse is actually several thousand times brighter than the sun. The sun is the brightest star as measure by apparent magnitude, which is how bright a star looks from a given location and depends on both absolute magnitude and distance.
How does apparent magnitude of a star differ from absolute magnitude?
Apparent magnitude is the brightness as observed from earth, while absolute magnitude is the brightness of a star at a set distance. The apparent magnitude considers the stars actual brightness as well as it's distance from us, but absolute magnitude takes the distance factor out so that star brightnesses can be directly compared.
Is the star's apparent magnitude the intrinsic property of a star?
No. Absolute magnitude is an intrinsic property of the star, but apparent magnitude also depends on the star's distance from Earth.
