Red giant branch star
WebRed supergiants ( RSGs) are stars with a supergiant luminosity class ( Yerkes class I) of spectral type K or M. [1] They are the largest stars in the universe in terms of volume, although they are not the most massive or luminous.

Webη Geminorum is a triple system, with the luminous class M star having a close companion known only from radial velocity variations, and a more distant companion resolved visually. In 1881, Burnham observed that η Geminorum had a close companion (η Gem B). At that time the separation was measured to be 1.08". [24] WebBetelgeuse is a mere 10 million years old, which is relatively young compared with our Sun’s 4.5 billion years, but it is already nearing its death throes as a red supergiant. Figure 3. Betelgeuse: Betelgeuse is in the constellation Orion, the hunter; in the right image, it is marked with a yellow "X" near the top left.
WebDec 12, 2024 · The Red Giant Branch phase is when the core is helium, but it has not yet begun fusing into heavier elements such as Oxygen and Carbon. When the Helium core collapsed into a giant red branch Star and started to fuse, it turned into a Horizontal Branch Star. Hydrogen is still fusing in the outer layers but not at the core.

WebMar 23, 2024 · Red Giant Branch Stars are stars that have left the Main Sequence phase of their life and have moved on to the next. During the Main Sequence phase, a star will fuse hydrogen into helium in the core. Once it has used all the hydrogen at the core, it will move on to this stage.
WebIn the last few years, the modeling of asymptotic giant branch (AGB) stars has been much investigated, both focusing on nucleosynthesis and stellar evolution aspects.
