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.

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.
Which star would have the greatest absolute magnitude?
The star with the greatest absolute magnitude is typically a supergiant star, such as a blue supergiant like Rigel or a red supergiant like Betelgeuse. These stars can have absolute magnitudes of around -6 to -12, depending on their size and luminosity. In contrast, the absolute magnitude of our Sun is about +4.83, illustrating the immense brightness of supergiants compared to other stars. Generally, more massive stars tend to have more negative absolute magnitudes, indicating higher luminosity.
What type of relationship is shown on a HR diagram?
It is a chart showing a scatter chart of stars according to their temperature and their luminosity (or absolute magnitude).
What is the absolute magnitude of this star m equals 6?
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.
What is the luminosity of polaris?
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.
Which means the same as luminosity?
Absolute magnitude.
Does apparent magnitude refer to real luminosity?
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.
What is thuban the stars luminosity?
Its absolute magnitude is -1.20.Its magnitude from our point of view is +3.65.
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.
How is luminosity related to absolute magnitude?
Luminosity refers to the total amount of energy a star emits per unit time, while absolute magnitude is a measure of a star's intrinsic brightness as seen from a standard distance of 10 parsecs. The absolute magnitude is directly related to luminosity; a lower absolute magnitude indicates a higher luminosity. The relationship between the two can be quantified using the distance modulus formula, which allows astronomers to compare the brightness of celestial objects regardless of their distance from Earth.
What is a synonym for absolute magnitude and apparent 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.
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 relationship between luminosity and absolute magnitude in stars?
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.
What would be the absolute magnitude and color of a main sequence star with a luminosity of 100?
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.
What is the relationship between the absolute magnitude and luminosity of a celestial object?
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.
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 star is brighter Betelgeuse or Rigel?
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.
