A Y-type star is a star within the Y-class, a spectral class indicating a star with a noticeable absorption line at wavelength 1.55 μm and a surface temperature under 700 K, which encompasses the coolest brown dwarfs (Y dwarfs). The spectral energy distribution (SED) peaks in the mid-infrared range.

How hot is an F star?

These stars have from 1.0 to 1.4 times the mass of the Sun and surface temperatures between 6,000 and 7,600 K. This temperature range gives the F-type stars a whitish hue when observed by the atmosphere.
