Mass and age.
What else can I help you with?
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.
Why is it important to know the absolute magnitude of stars?
Knowing the absolute magnitude of stars is crucial because it allows astronomers to determine their intrinsic brightness, independent of their distance from Earth. This helps in comparing the true luminosities of different stars and understanding their evolutionary stages. Additionally, absolute magnitude is essential for calculating distances to stars using methods like the distance modulus, which enhances our understanding of the structure and scale of the universe.
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 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 is the absolute magnitude of cassiopeia?
Cassiopeia is a constellation, not a single star, so it does not have a specific absolute magnitude. The stars within the constellation Cassiopeia have a range of absolute magnitudes depending on their distance and luminosity.
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 is the approximate absolute magnitude of Rigel?
The approximate absolute magnitude of Rigel is about -7.0. This makes it one of the brightest stars in the night sky.
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 is the magnitude of Rigel?
Rigel has an apparent magnitude of around 0.12, making it one of the brightest stars in the sky. Its absolute magnitude, which measures intrinsic brightness, is around -7.0, indicating its high luminosity.
