Web30 okt. 2024 · When the stars go out Eventually, a main sequence star burns through the hydrogen in its core, reaching the end of its life cycle. At this point, it leaves the main sequence. Then the pressure of fusion provides an outward thrust that expands the star several times larger than its original size, forming a red giant. WebAs most massive Star grows old, it may first expand to become a Red Giant. If matter escapes the Roche lobe of the red giant, it may fall onto the companion star, resulting in Mass Transfer. This can change the evolution of the stars (determined by mass) Resulting in a mysterious age-mass relationship where the heaviest star is least evolved
