WebApr 13, 2024 · The relative amount of harmful radiation (to life as we know it) that stars emit can be 80 to 500 times more intense for M dwarfs relative to our Sun, but only 5 to 25 times more intense for the orange K dwarfs. Red dwarfs make up the bulk of the Milky Way's population, about 73%. WebOf the red stars observed by Hertzsprung, the dwarf stars also followed the spectra-luminosity relationship discovered by Russell. However, giant stars are much brighter than dwarfs and so do not follow the same relationship. Russell proposed that "giant stars must have low density or great surface brightness, and the reverse is true of dwarf ...

WebThe Sun formed from a collapsing globule ~4.57 billion years ago, and it contains suﬃcient hydrogen fuel to persist as a normal star for another ~5.4 billion years. When it runs out of fuel, it will spend ~120 million years as a giant star, and then it will become a nebula with a central white dwarf. Figure 2.32. WebA K-type main-sequence star, also referred to as a K-type dwarf or an orange dwarf, is a main-sequence ( hydrogen -burning) star of spectral type K and luminosity class V.
