How long do F-type stars spend fusing hydrogen on the main sequence compared to G-type stars?
F-type stars spend between 2 billion and 6 billion years fusing hydrogen on the main sequence which is significantly shorter than the 10 billion years required for G-type stars like our Sun.
Which nearby systems host confirmed exoplanets orbiting F-type stars such as Upsilon Andromedae or Tau Boötis?
Upsilon Andromedae hosts one of the nearest known planetary systems orbiting an F-type star while Tau Boötis contains planets that circle this bright stellar type along with HD 10647 and HD 33564.
What are the habitable zone distances and UV radiation risks for F0 and F8 stars?
The habitable zone for a relatively hot F0 star extends from about 2.0 AU to 3.7 AU while a cooler F8 star offers a narrower range between 1.1 and 2.2 AU.
