If the star is 0.5 solar masses (half the mass of our sun), electron degeneracy pressure will prevent the star from collapsing in upon itself. Due to the age of the universe, scientists can only use computer modeling to predict what will happen to such a star. ... We have written many articles about stars on Universe Today.

Post-Main Sequence Stars section of astrophysics option for NSW HSC Physics course. ... Evolution of High-Mass Stars Post-Main Sequence ... Evolution of high-mass stars off the main sequence is an involved process and one still not fully understood. Such stars are rare and have very short lifespans relative to lower-mass stars.

In general, main sequence stars have chemical compositions similar to that of the Sun. The higher the mass of the main sequence star, the greater its diameter and the higher its surface temperature. ... The classes are actually derived from the stars' spectra. The stellar astronomer's greatest tool is the HR diagram,
