G-type star
Définition(s)
- A G star is a yellowish star of spectral type G, with a surface temperature in the range 5,000 to 5,800°C and mass of 0.8 to 1.1 solar masses. G stars have spectra containing many absorption lines of neutral and ionized metals, together with some molecular absorption bands. The H and K lines of ionized calcium are particularly strong. Main sequence G stars, of which the Sun and Alpha Centauri A are examples, are the prime targets of searches for exoplanets and targeted SETI programs.
