main sequence definition

  • noun:
    • A major grouping of performers that types a comparatively slim musical organization from the upper remaining to the lower right whenever plotted based on luminosity and area heat in the Hertzsprung-Russell diagram.
    • That region on a two-dimensional graph of luminosity versus heat for movie stars (the Herzsprung-Russel drawing), which operates from high-temperature and high luminosity to low temperature and low luminosity, for which a lot of the stars (plotted as things in the diagram) are observed. A normal celebrity like the planet's sunlight will spend the majority of its time over vast amounts of years within this region of heat and luminosity, because progressively converts more of its initial hydrogen into weightier elements. After the hydrogen is eaten, a star could become a red giant or evolve into other forms of star maybe not within the primary series area.
  • proper-noun:
    • : an important grouping of performers that creates a narrow musical organization from the top remaining toward reduced right when plotted by luminosity and surface heat on a Hertzsprung-Russell diagram.
    • The area on the Hertzsprung-Russell diagram when the primary series is situated
