Why do astronomers still prioritize observing G-type stars, even if K-dwarfs show better potential?
Answer
G-type stars are easier to study observationally due to their higher light output.
The prioritization in astronomical observation often involves a pragmatic balance between biological potential and observational feasibility. While K-dwarfs are analytically deemed the most suitable targets for hosting life due to their immense stable timescales, G-type stars, such as the Sun, possess a higher light output. This increased luminosity makes them significantly easier targets for current high-powered telescopes, like the Hubble Space Telescope, to study and characterize accurately regarding planetary systems and atmospheric compositions. Therefore, G-stars remain important benchmarks and targets for ongoing research efforts.
