Which stars represent the majority of the total star count in the universe, despite their low brilliance?
Answer
Long-lived, low-mass red and yellow dwarfs
Although massive, bright stars dominate the visual light output of any stellar population because of their immense luminosity, they represent only a small fraction of the total number of stars present. The vast majority of stars in the universe are composed of low-mass stars, such as red and yellow dwarfs. These less massive stars utilize slower, less efficient fusion pathways, allowing them to conserve their hydrogen fuel reserves and maintain stable main-sequence lifetimes that can extend for trillions of years, making them the most numerous stellar objects observed over cosmic timescales.
