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.
What is the actual amount of light a star gives off?
It is actually absolute magnitude, opposed to apparent magnitude which is how much light stars appear to give off.
What two things does a stars absolute magnitude depend?
Mass and age.
What are stars with low magnitude low temperature and low absolute magnitude?
This probably refers to red dwarves. The apparent magnitude depends on the distance, as well as the absolute magnitude, but even the closest red dwarves can't be seen with the naked eye.
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 is the absolute magnitude of the constellation scorpius?
Constellations don't have an absolute magnitude. That is a property of individual stars.
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.
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.
What is the magnitude of a star if all stars were the same distance from earth?
Absolute magnitude
What are two ways to describe a stars brightness?
Apparent magnitude and absolute magnitude.
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.
What is thuban the stars luminosity?
Its absolute magnitude is -1.20.Its magnitude from our point of view is +3.65.
What is true about the absolute magnitude and temperature of supergiant stars?
Absolute magnitude: they are extremely bright. Temperature: their surface temperature is fairly low.
What do you call the real brightness of the stars?
The term is "absolute magnitude".
What is the actual amount of light a star gives off?
It is actually absolute magnitude, opposed to apparent magnitude which is how much light stars appear to give off.
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.
What two things does a stars absolute magnitude depend?
Mass and age.
