WebOct 30, 2024 · Life on Earth will not be adversely affected when nearby stars become red giants. Certainly, things will get very messy inside those systems: red giants throw out a lot of gas and dust. Red giants are a lot more luminous than the Sun because they have such a huge surface area, but they don't emit large amounts of dangerous radiation, like X … WebRed supergiants quickly collapse, producing a giant explosion called a supernova. High mass red supergiants form neutron stars. where the core of the supergiant (about 1.5 times the mass of the ...
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 surface temperature around 5,000 K (4,700 °C; 8,500 °F) or lower. The appearance of the red giant is from … 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 hundreds of times larger than that of the 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.

A small number of progenitors of type II-L and type IIb supernovae have been observed, all having luminosities around 100,000 L ☉ and somewhat higher temperatures up to 6,000K. These are a good match for slightly higher mass red supergiants with high mass-loss rates.
