Main sequence star classification

WebA G-type main-sequence star (spectral type: G-V), also often, and imprecisely called a yellow dwarf, or G star, is a main-sequence star (luminosity class V) of spectral type G. Such a star has about 0.9 to 1.1 solar masses and an effective temperature between about 5,300 and 6,000 K.Like other main-sequence stars, a G-type main-sequence star … WebMar 19, 2024 · Star classification often depends on the mass of these suns—the biggest burn hottest and brightest, while other types of stars are cooler and longer-lived. ... Stars in the prime of their lives, known as main sequence stars, are typically classified by how hot they are. Since most star temperatures can’t be directly measured, ...
