F Class stars have the following characteristics.
Spectral class is a classification system for stars based on their temperature and spectral characteristics. It categorizes stars into different groups, such as O, B, A, F, G, K, and M, with O being the hottest and M being the coolest. Spectral class is indicated by a letter, with additional subtype information denoted by a number.
O. This is the class of the blue/white giants.
The sun belongs to the class of stars known as G-type main sequence stars.
B Class stars have the following characteristics.Temperature: 10,000 -> 30,000 KelvinColour: Blue -> Blue-whiteMass: 2.1 -> 16 Solar massesRadius: 1.8 -> 6.6 Solar radiusLuminosity: 25 -> 30,000 Solar luminosities.Rarity: 0.13% of all main sequence stars.Examples: RigelSee related link for more information.
The largest class of stars are known as hypergiants. These massive stars have very high luminosities and can be hundreds of times bigger than the Sun. Examples include stars like UY Scuti and Betelgeuse.
The spectral class letters in astronomy represent the temperature and color of stars. The sequence starts with O (hottest and bluest stars) and ends with M (coolest and reddest stars). The spectral class letters are O, B, A, F, G, K, and M.
Class II: yellow stars-hydrogen less strong, but evident metallic lines, such as the Sun, Arcturus and Capella. This includes the modern classes G and K as well as late class F.
Falling star, flight, Fomalhaut, F-ring of Saturn, F-class stars, Fishes (Pisces), Fornax.

Polaris is a multiple star system comprising mainly F class stars. It may well be a open cluster contain a mixture of A and F class stars.The main star - Polaris A is about 6,000 -> 7,500 kelvinits estamated to be around 5,700C (10,300F)
O. This is the class of the blue/white giants.
