F-type main-sequence star

Gray & Garrison (1989) provide a modern table of dwarf standards for the hotter F-type stars.

F1 and F7 dwarf standards stars are rarely listed, but have changed slightly over the years among expert classifiers.

Some studies show that there is a possibility that life could also develop on planets that orbit an F-type star.

[14] F-type stars are known to emit much higher energy forms of light, such as UV radiation, which in the long term can have a profoundly negative effect on DNA molecules.

[14] Studies have shown that, for a hypothetical planet positioned at an equivalent habitable distance from an F-type star as the Earth is from the Sun (this is farther away from the F-type star, outside the habitable zone of a G2-type), and with a similar atmosphere, life on its surface would receive about 2.5 to 7.1 times more damage from UV light compared to that on Earth.

[14] Without a robust ozone layer, life could theoretically develop on the planet's surface, but it would most likely be confined to underwater or underground regions or has somehow adapted external covering against it (e.g.
