Definition von main-sequence im Englisch Englisch wörterbuch
Of or dealing with a major group of stars forming a band stretching from upper left to lower right on a Hertzsprung-Russell diagram when being plotted by luminosity and surface temperature
The area on the Hertzsprung-Russell diagram in which the main sequence is located
: A major grouping of stars that creates a narrow band from the upper left to the lower right when plotted by luminosity and surface temperature on a Hertzsprung-Russell diagram
(Astronomi) The main sequence is a continuous and distinctive band of stars that appears on plots of stellar color versus brightness. These color-magnitude plots are known as Hertzsprung–Russell diagrams after their co-developers, Ejnar Hertzsprung and Henry Norris Russell. Stars on this band are known as main-sequence stars or "dwarf" stars

The stable phase of a star's lifetime, when outward pressure from internal fusion process using hydrogen for fuel is balanced by the inward force of self-gravitation This phase is usually the longest phase of a star's lifetime Our Sun is a main sequence star
A major grouping of stars that forms a relatively narrow band from the upper left to the lower right when plotted according to luminosity and surface temperature on the Hertzsprung-Russell diagram
A group of stars on the HR diagram that all shine via hydrogen thermonuclear fusion, and are all in a state of hydrodynamic equilibrium Stars spend the greatest portion of their luminous (nuclear fusion) life on the main sequence
the narrow diagonal band in the Hertzsprung-Russell diagram going from upper left to lower right describing the characteristics of 90% of the stars Stars spend about 90% of their lives in this stage and are fusing hydrogen to create helium
the section of the HR Diagram that runs from the upper-left hand corner to the lower-right hand corner and characterizes stars in the main stage of their life; the stage at which they fuse hydrogen and helium in their core
