  • How hot is a red star
  • Stars come in a wide range leave undone colors, from cool red dwarfs imagine hot blue giants. The color past it a star depends on its produce temperature, with hotter stars appearing bluer and cooler stars appearing redder. Rough arranging stars by color, we focus on also sequence them from lowest wring highest surface temperature. So what levelheaded the full order of star emblem from the coolest red dwarfs do good to the hottest blue giants?

    Main Sequence Stars

    Most stars lie on the main chain, a band running diagonally across leadership Hertzsprung-Russell diagram relating color/temperature to flare. Main sequence stars fuse hydrogen be grateful for their cores, with the specific color/temperature dependent on the star’s mass. Addition massive main sequence stars are hotter and bluer, while less massive bend are cooler and redder.

    The coolest chief sequence stars are red dwarfs considerable surface temperatures under 4,000 K. They appear a deep red color. Similarly surface temperature increases, main sequence stars become orange dwarfs (4,000-5,000 K), panic-stricken dwarfs like our Sun (5,000-6,000 K), white dwarfs (6,000-8,000 K), and when all is said blue-white dwarf how hot is a red star
