According to, [3] the greatest change in UV irradiance occurs in a planet orbiting an F0 star with >1.5 M ☉︎, as opposed to an F8 or F9 star with ≤1.2 M ☉︎. The most dangerous phase in a star's life for potentially habitable planets orbiting it would be the earliest, between the star's formation and its 500 Mya -milestone, especially ...
Disc of debris around an F-type star, HD 181327. [1] An F-type main-sequence star (F V) is a main-sequence, hydrogen-fusing star of spectral type F and luminosity class V. 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. [2] Tables VII and VIII.
TOI-1338 is a single-lined spectroscopic binary system, consisting of an F8 star and a red dwarf of spectral type M. The system has an age of 4.4 billion years. The two stars with masses of 1.13 and 0.313 M ☉ revolve around each other every 14.6 days.

Surface planetary habitability is thought to require an orbit at the right distance from the host star for liquid surface water to be present, in addition to various geophysical and geodynamical aspects, atmospheric density, radiation type and intensity, and the host star's plasma environment.
Artist's impression of Kepler-62f orbiting the orange dwarf star Kepler-62.. A star's characteristics is a key consideration for planetary habitability. [6] The types of stars generally considered to be potential hosts for habitable worlds include F, G, K, and M-type main-sequence stars. [7]
