Explanation HR diagram gives the information of stars. Stars are classified on the basis of luminosity, spectral type, temperature and absolute magnitude. From HR diagram, absolute magnitude of any star can be estimated with the help of its spectral type. From above figure, it can be estimated that stars of spectral type G2 have an absolute magnitude of 4.5. Here, spectral type of Rigel Kentaurus is G2. Therefore, absolute magnitude of Rigel kentaurus is 4.5. Similarly, absolute magnitude can also be estimated for other stars from the above HR diagram...

Stellar evolution

We may see thousands of stars in the dark sky. Our universe consists of billions of stars. Stars may appear tiny to us but they are huge balls of gasses. Sun is a star of average size. Some stars are even a thousand times larger than the sun. The stars d…
