Sounds like you've put a lot of entropy and theropy into this question. but seriously the answer is actually 42. Also you spelled temperature wrong. sorry to be so picky. it was probably a key stroke error. not to call you an incompetent typist. by the way, you also spelled gravitational wrong. do you use spell check? it is really simple. all you have to do is click the little button with the abc and check mark. it would probably help so you can stop butchering such simple words. again, sorry about being so picky. it is just a habit i have. i just feel that grammatical errors should be corrected. i should be a teacher. that would be fun. i would have so much fun. i would make it fun for all the students so they would like school. hopefully we never meet or i might have to force a dictionary into your walnut sized scrap of garbage you call a brain.
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
It is a chart showing a scatter chart of stars according to their temperature and their luminosity (or absolute magnitude).
The absolute magnitude of a star is a measure of its true brightness if it were placed at a standard distance of 10 parsecs from Earth. To calculate the absolute magnitude from the apparent magnitude (m) of 6, you would need to know the star's distance. Without this information, we cannot determine the absolute magnitude.
Polaris has an absolute visual magnitude of about -3.2, making it over 4,000 times more luminous than the Sun. Its luminosity is approximately 1,200 times that of the Sun in terms of total energy output.
The luminosity of a star gives the most information about its physical nature. Luminosity is a measure of how much energy a star emits per unit of time and is directly related to its size, temperature, and distance. By knowing a star's luminosity, scientists can determine its mass, age, and evolutionary stage.
Absolute magnitude.
No. Apparent magnitude (or luminosity) means how bright a star (or other object) looks to us; absolute magnitude (or luminosity) refers to how bright it really is.
Its absolute magnitude is -1.20.Its magnitude from our point of view is +3.65.
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
Apparent magnitude: How bright something looks to us. Absolute magnitude: How bright something really is - expressed as the apparent magnitude it would have at a standard distance.
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.
The relationship between luminosity and absolute magnitude in stars is that luminosity measures the total amount of energy a star emits, while absolute magnitude measures the brightness of a star as seen from a standard distance. Stars with higher luminosity have lower absolute magnitudes, meaning they appear brighter in the sky.
The absolute magnitude depends on the luminosity and distance, whereas the color depends on the temperature of the star. Without the distance information, we can't determine the absolute magnitude. For a main sequence star with a luminosity of 100 times that of the Sun, it would likely fall in the range of spectral classes O to F, appearing blue-white to white in color.
The absolute magnitude of a celestial object is a measure of its brightness as seen from a standard distance, while luminosity is the total amount of energy a celestial object emits per unit time. The relationship between absolute magnitude and luminosity is that a higher absolute magnitude corresponds to a lower luminosity, and vice versa. In other words, the absolute magnitude and luminosity of a celestial object are inversely related.
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.
Betelgeuse has an apparent magnitude of 0.42(v) and an absolute magnitude of -6.02. Rigel has an apparent magnitude of 0.12 and an absolute magnitude of -7.04. So Rigel is brighter.
Magnitudes require distance and luminosity. Therefore a specific star is required.
