How do stars become red giants
Very-high-mass stars develop into supergiants that follow an evolutionary track that takes them back and forth horizontally over the H–R diagram, at the right end constituting red supergiants. These usually end their life as a type II supernova. The most massive stars can become Wolf–Rayet stars without … See more A red giant is a luminous giant star of low or intermediate mass (roughly 0.3–8 solar masses (M☉)) in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous, making the radius large and the … See more A red giant is a star that has exhausted the supply of hydrogen in its core and has begun thermonuclear fusion of hydrogen in a shell surrounding the core. They have radii tens to … See more Red giants with known planets: the M-type HD 208527, HD 220074 and, as of February 2014, a few tens of known K-giants including Pollux, Gamma Cephei and Iota Draconis. Prospects for habitability Although … See more The Sun will exit the main sequence in approximately 5 billion years and start to turn into a red giant. As a red giant, the Sun will grow so large (over 200 times its present-day radius) that it will engulf Mercury, Venus, and likely Earth. See more Red giants are evolved from main-sequence stars with masses in the range from about 0.3 M☉ to around 8 M☉. When a star initially forms from a collapsing molecular cloud in … See more Many of the well-known bright stars are red giants, because they are luminous and moderately common. The red-giant branch variable star Gamma Crucis is the nearest M-class giant star at … See more Media related to Red giants at Wikimedia Commons See more 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

WebA Red Giant star is formed when a star like our sun, or one larger, runs out of its hydrogen fuel. Inside a star, hydrogen atoms are combined together to form helium atoms. This process creates the energy that the star needs to resist the force of gravity that is trying to crush the star together, and also causes the star to light up. WebIt has entered its second red giant phase. What happens next depends on the mass of the star. Low-mass, Sun-like stars enter the planetary nebula stage.

The core of a red giant is contracting, but the outer layers are … WebRed supergiants develop from main-sequence stars with masses between about 8 M☉ and 30 or 40 M☉. [10] Higher-mass stars never cool sufficiently to become red supergiants.
WebMay 7, 2015 · The star has become a red giant. What happens next in the life of a star depends on its initial mass. Whether it was a "massive" star (some 5 or more times the mass of our Sun) or whether it was a "low or medium mass" star (about 0.4 to 3.4 times the mass of our Sun), the next steps after the red giant phase are very, very different.
