As shown in a Hertzsprung-Russel diagram the main-sequence stars are defined according to their?
Absolute magnitude and surface temperature
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 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.
What are the two main properties that astonomers use to classify stars?
The surface temperature and the absolute magnitude, which is the brightness of the star when viewed from a standard distance of 10 parsecs.
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.
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 a graph that shows the relatonship between stars surface temperature and its absolute magnitude?
That is called the Hertzsprung-Russell or HR diagram and each star occupies a point. The horizontal axis is temperature and the vertical axis is the absolute magnitude.
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.
What is the absolute magnitude of the constellation scorpius?
Constellations don't have an absolute magnitude. That is a property of individual stars.
What graph shows the relationship of a stars absolute magnitude and its temperature?
Its called an HR diagram or a Hertzsprung-Russell diagram.
As shown in a Hertzsprung-Russel diagram the main-sequence stars are defined according to their?
Absolute magnitude and surface temperature
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.
The distances to nearby stars can be measured by using . a. absolute magnitude c. color b. temperature d. parallax?
preallax
As shown in a H-R diagram the main-sequence stars are defined according to their?
They are defined by their absolute magnitude and surface temperature.
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 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 the magnitude of a star if all stars were the same distance from earth?
Absolute magnitude
