F-type main-sequence stars are expected to remain stable for about 2 to 4 billion years as detailed models suggest. (Our Sun should have a correspondingly stable lifetime of approximately 10 billion years.)

How common are F-type stars?
F-type stars represent 3 percent of the stars in the Milky Way, as compared with G-class at about 7 percent and K-class at approximately 12. And then there are M-dwarfs, which may account for over 75 percent of all main sequence stars.
Can a type stars support life?
Compared to other stars, A – type stars offer a large Habitable Zone. If we place Sirius in Solar System, life can brought even on Sedna! The outer limit of extended habitable zone is so far that it might extend out of Sirius’s magnetosphere.
Can F-type stars have planets?
Planets have been discovered around F – type stars, like the one found around Tau Bootis. These stars can develop planetary systems similar to Solar System. Distance and orbit: A planet in the center of Habitable Zone must be located around 1.5 AU from hosting star.
How long do type B stars live?
stellar associations …of spectral types O and B. They have absolute luminosities as bright as any star in the Galaxy—on the order of one million times the luminosity of the Sun. Such stars have very short lifetimes, only lasting a few million years.
Do F-type stars go supernova?
They are mainly seen as White Stars but some pale blue stars are also seen as F stars. G.S.U. U.C.L. If their mass is high enough, they will explode at the end of their life in a supernova explosion otherwise will become a Planetary Nebula.
How long do G stars live?
A G-type main-sequence star will fuse hydrogen for approximately 10 billion years, until it is exhausted at the center of the star.
What color are F-type stars?
F-type stars are yellow-white, reach 6,000–7,400 K, and display many spectral lines caused by metals.
What is the best type of star for life?
“K-dwarf stars are in the ‘sweet spot,’ with properties intermediate between the rarer, more luminous, but shorter-lived solar-type stars (G stars) and the more numerous red dwarf stars (M stars). The K stars, especially the warmer ones, have the best of all worlds.
How many planets are in 100 light years?
All the 24 exoplanets are located over 100 light-years away.
Can blue stars support life?
A star may be unsuitable for life for other reasons: it may be prone to extreme flares, for example. A blue giant is a star that burns bright and dies young, only lasting a few million years. Planets around such a star would have only just formed (they may still have molten surfaces).
What is the lifespan of Procyon star?
The mass of the progenitor star for Procyon B was about 2.5 solar masses and it came to the end of its life some 1.7 billion years ago, after a main sequence lifetime of 400-600 million years. For this reason, the age of Procyon A is expected to be at least 2 billion years.
How long does a supernova last for?
The explosion of a supernova occurs in a star in a very short timespan of about 100 seconds. When a star undergoes a supernova explosion, it dies leaving behind a remnant: either a neutron star or a black hole.
How long do M type stars live?
The lifetimes of main sequence stars therefore range from a million years for a 40 solar mass O-type star, to 560 billion years for a 0.2 solar mass M-type star.
What is the rarest star type?
An O-type star is a hot, blue-white star of spectral type O in the Yerkes classification system employed by astronomers. They have temperatures in excess of 30,000 kelvin (K).
