  • Stellar Evolution

    The source of energy for the main sequence stars is nuclear fusion of hydrogen into helium whereas that in red giant stars and super giant stars is nuclear fusion of helium into carbon.

  • Hertzsprung-Russell diagram

    So clusters with a lot of blue giants are younger than clusters with a lot of main sequence starts. clusters with a majority of main sequence stars are younger than clusters with a lot of red giants.

  • main sequence G2 V type star

    The main sequences for G2 V type stars are examined.

  • Electromagnetic spectrum spread of star energy

    As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion.

  • Astrophysics: Absorption Lines, Spectral Classes, and the Sun

    For the cluster 1, the cooler star which is present in the main sequence is of spectral type K. All the other low mass stars are in pre-main sequence phase, which means they are in the process of evolving to the main sequence.

  • The Hertzsprung-Russel Diagram

    But often, all stars stay in the 'middle' where the path runs from top-left to lower-right as part of the main sequence movement.

  • basic astronomy questions

    0.4 parsecs 2.5 parsecs 17 parsecs 40 parsecs Four stars of different mass arrive on the Main Sequence of the Hertzsprung-Russell Diagram at the same time. Which star will depart the Main Sequence first?

  • Stellar Evolution Discussed

    A star that burns hydrogen in its core is called a main sequence star. The Sun is an example of a main sequence star. During these stages, the major forces that stabilize a star are the gravity and the thermal pressure.

  • Masses of X-Ray Binary Stars

    This is from a conversion of the mass of the main sequence star into x-ray photons.
