Web17 sep. 2024 · The star has started evolving into what is known as a subgiant star, representing an intermediate phase between the main sequence and the red giant … WebDuring the main sequence, the star is supported by the fusion of hydrogen into helium. Eventually, the hydrogen runs out at the centre, so hydrogen fusion is no longer possible there. Why doesn't it start fusing helium into carbon right away? That's because the core isn't hot or dense enough yet. recycling refrigerators in wisconsin

WebRed Giant A red giant forms after a star has run out of hydrogen fuel for nuclear fusion, and has begun the process of dying. A star maintains its stability through a fine balance between its own gravity, which holds it together, and the outwards pressure from ongoing thermonuclear fusion processes taking place at its core. recycling reduces waste

Twinkling Stars Supply the Dust That Leads to Life

WebA red giant is a star in the later stages of its stellar life. It is said that stars only spend 1% of their lives in this stage. Our Sun is now in the main sequence. It generates energy by converting hydrogen into helium. In the main sequence, the core of a star is in a state of hydrostatic equilibrium. WebAlso, stars that have the same luminosity as dimmer main sequence stars, but are to the left of them (hotter) on the H-R diagram, have smaller surface areas (smaller radii). Bright, cool stars are therefore necessarily very large. These enormous stars are called Red Giants and lie above the main sequence line. Antares is a good example of a red ...
