Our Sun is a G-type star, but it is in fact white. They have temperatures between 5,200 K to 7,500 K and luminosities around 0.6 to 5.0 times that of the Sun. They last about 4 to 17 billion years.

WebThe giant branch and supergiant stars lie above the main sequence, and white dwarfs are found below it. Credit: R. Hollow, CSIRO. This Hertzsprung-Russell diagram shows a group of stars in various stages of their evolution. The term was originally coined in 1906 when the Danish astronomer Ejnar Hertzsprung noticed that the reddest stars – classified as K and M in the Harvard scheme – could be divided into two distinct groups. They are either much brighter than the Sun, or much fainter. To distinguish these groups, he called them "giant" and "dwarf" stars, the dwarf stars being fainter and the giants being brighter than the Sun. pontoon cleaning and polishing

WebPrevious work has shown that the core accretion mechanism does not seem to be able to form gas giant planets around M dwarfs, because the time required for core formation scales with the orbital period, which lengthens for lower mass stars, resulting in failed (gas-poor) cores unless the gaseous protoplanetary disk survives for > 10 absent 10 ...
