G-type star

A G-type star is a star within the G-class, a spectral class for stars with metal and weak hydrogen absorption lines, a yellow color and a surface temperature in the range of 5300-6000 K. The spectral energy distribution (SED) peak is within the visible range. The Sun is a main sequence star within this class. Such main sequence stars (aka yellow dwarfs or G dwarfs) burn their hydrogen in on the order of ten billion years. Characteristics of G-type main sequence stars:

Some example G-type stars are Alpha Centauri and T Tauri (a pre-main-sequence star). Giant stars can also fall in the G-class (yellow giants), including supergiants (yellow supergiants) and hypergiants (yellow hypergiants).
