I am given the bolometric BC equals -1.46 and the visual magnitude V equals 4.33 of a star. how do you calculate the angular diameter?
The bolometric correction allows you to convert between visual and bolometric (total) magnitude - where the bolometric magnitude includes all radiation emitted by the star, not just visible light. It has nothing to do with the angular diameter.
What is the magnitude of the star alioth?
what is the magnitude of the star Alioth in the constellation Ursa Major
Is a high magnitude star more dense than a low magnitude star?
Magnitude is a measure of brightness, there is no relationship with density.
What is difference in a star's apparent magnitude and absolute magnitude caused by?
How far away the star is.
Is it true or false a third-magnitude star is ten times as bright as a fourth -magnitude star?
True.
How does the magnitude of a star effect it's brightness?
The brightness of a star is not affected by its magnitude/size but is instead affected by the heat at which the star burns.
How diameter and absolute magnitude related?
the larger the mass of the star, the more luminous it is.
How does a star's temperature affect its absolute magnitude?
The absolute magnitude of a start will increase both:* If its surface temperature increases, and * If its diameter increases.
Why does a star look smaller than another star but is bigger than the other star?
Normally you would observe the star's brightness, not its apparent diameter.The star's apparent brightness ("apparent magnitude") depends on its real brightness ("absolute magnitude"), and on the distance. Similarly, the star's apparent angular diameter (which is VERY hard to measure) would depend on its actual diameter, and on the distance.

What is a star brightness called?
the brightness of a star is called it's magnitude
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.
What is star's magnitude?
The magnitude is the brightness of the star.
What star is called its magnitude?
The magnitude of a star means how bright it is.
A first magnitude star is times brighter than a 5th magnitude star?
For apparent magnitudes, a magnitude of zero has the same magnitude as Vega. A first magnitude star is 40 percent as bright and a fifth magnitude star is one percent. So, a first magnitude star is 40 times as bright as a fifth.
What is the magnitude of a star as it appears in the sky called?
The Polar star is the star that is magnitude. This is a Luminosity star.
What is the distance between an eighth magnitude star and a 9th magnitude star?
The 8th magnitude star is about 2.5 times brighter.
