Stellar evolution after the main sequence (low-mass version)

WebThe Giant Branch: Red giants are luminous, cool giant stars in spectral classes F, G, K, and M located in the middle right portion of the H-R diagram, above the main sequence. As the central core of a main sequence star with a mass from ~0.8 to 8 solar masses runs out of hydrogen, radiation pressure no longer balances gravity and the star begins to collapse. Web14 dec. 2024 · Another difference would just be the number of stars. A typical globular cluster might have > 10 5 stars, whereas a typical open cluster might have more like ∼ 10 3. This means the various features in the HR diagram are much better delineated in a globular cluster - the turn-off, a red giant branch and a horizontal branch.

WebAs it evolves along the red giant branch, it swells and so becomes brighter and cooler. This stops when the star reaches the helium flash, and then it quickly moves to the horizontal … The red-giant branch (RGB), sometimes called the first giant branch, is the portion of the giant branch before helium ignition occurs in the course of stellar evolution. It is a stage that follows the main sequence for low- to intermediate-mass stars. Red-giant-branch stars have an inert helium core surrounded by a shell of hydrogen fusing via the CNO cycle. They are K- and M-class stars muc… When a star exhausts the supply of hydrogen by nuclear fusion processes in its core, the core contracts and its temperature increases, causing the outer layers of the star to expand and cool. The star becomes a red giant, following a track towards the upper-right hand corner of the HR diagram. Eventually, once the temperature in the core has reached approximately 3×10 K, helium burning (fusi…
