What star type is F?
What star type is F?
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. This temperature range gives the F-type stars a yellow-white hue.
What color are F stars?
F-type stars are yellow-white, reach 6,000–7,400 K, and display many spectral lines caused by metals. The Sun is a class G star; these are yellow, with surface temperatures of 5,000–6,000 K.
What are F-type stars made of?
F-Type Stars Facts They are Main Sequence stars, fusing hydrogen to helium. They are hotter than G-Type stars which the Sun is classed as one. They can have planets orbiting them. The Goldilocks Zone for a F-Type star is further from its stars than it would be for a Yellow star like our Sun.
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.
How long does an F type star last?
about 2 to 4 billion years
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.)
What is the least common type of star?
O stars
O stars are the least common and M are the most common found in the main sequence of stars. Stars near the beginning or end of their lives are not part of this classification.
How long do O type stars live?
The least luminous O-type stars can remain on the main sequence for around 10 million years, but cool slowly during that time and become early B-type stars. No massive star remains with spectral class O for more than about 5–6 million years.
