How To Find The Absolute Megnitude A Star

how to find the absolute megnitude a star

Solution-What is the absolute magnitude of a star
The absolute magnitude is the apparent magnitude IF the star would be at a distance of 10 parsecs away from Earth, and is thus a measure of the intrinsic brightness of the star regardless of distance.... Apparent magnitude, however, does not tell us about the intrinsic properties of the star, so it is necessary to use the concept of absolute magnitude. The absolute magnitude, M , of a star is defined as what the apparent magnitude of that star would be if …

How To Find The Absolute Megnitude A Star

The equation for the magnitude of a star is; M=m-5log(d/10) where: M - Absolute magnitude (The brightness of a star viewed 10 parsecs away) m - Apparent magnitude (The brightness of a star as viewed from Earth)d - Distance from the star (Pc).

  • Compare this to the brightest star in the sky that our eyes can see, Sirius, which has an absolute magnitude of 1.4, or a much dimmer star called Ross 458, which has an absolute magnitude of 14.8
  • Absolute magnitude can refer to either the absolute visual magnitude (which is measured by visible light) or the absolute bolometric magnitude (which is measured by light of all wavelengths). You're thinking of visual absolute magnitude; how bright an object would appear to our eyes if the object were 10 parsecs away from us. However, you must remember that stars emit a wide spectrum of light
  • It is the apparent magnitude of a star, were it to be observed at a distance of 10 parsecs or 32.6 light years. It is a standard yardstick that is used to measure the actual brightness of all stars …
  • Heres the question: A stars cluster 75,000 light years away is composed of 3,000 stars. 500 of these stars have an apparent magnitude m=20. another 500 have an apparent magnitude m=22 another 1,000 have an apparent magnitude m = 23 The final 1,000 stars have an apparent magnitude m=25. What is the integrated Apparent magnitude of the whole cluster?
