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 color is an O star?
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).
What are the Colours of stars?
Sirius, also called Alpha Canis Majoris or the Dog Star, brightest star in the night sky, with apparent visual magnitude −1.46. It is a binary star in the constellation Canis Major.
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.
What does OH a fine girl kiss me mean?
Every student in introductory astronomy learns the mnemonic “Oh Be a Fine Girl/Guy, Kiss Me”, which is a way to remember the spectral classification of stars. Oh: O class stars are the hottest, with peak temperatures in the ultraviolet part of the spectrum.
Do brown dwarfs have fusion?
Brown dwarfs are an odd set of objects that are neither planets nor stars. However, if a brown dwarf has at least 13 times the mass of Jupiter, it can ignite a limited form of fusion. These brown dwarfs fuse a heavy isotope of hydrogen, called deuterium, into helium, releasing energy like a star.
What are the 3 main types of stars?
So, let’s take a look at all the different types of stars that have been discovered so far.
- T Tauri Stars.
- Main Sequence Stars.
- Red Giant Stars.
- White Dwarf Stars.
- Red Dwarf Stars.
- Neutron Stars.
- Supergiant Stars.
Is the sun a dwarf star?
The Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It’s about 93 million miles (150 million kilometers) from Earth and it’s our solar system’s only star. Without the Sun’s energy, life as we know it could not exist on our home planet.
What color is the hottest star?
White stars are hotter than red and yellow. Blue stars are the hottest stars of all. Stars are not really star-shaped. They are round like our sun.
Are stars yellow or white?
As a matter of fact, all stars are not yellow. They appear “yellow-white” to a human eye because of the very dark-black background of the sky. And also because in the obscurity, the human eye does not use the same detectors to see than in the day light.
What color is Moon?
It depends on the night. Outside of the Earth’s atmosphere, the dark Moon, which shines by reflected sunlight, appears a magnificently brown-tinged gray. Viewed from inside the Earth’s atmosphere, though, the moon can appear quite different. A red or yellow colored moon usually indicates a moon seen near the horizon.
What is a blue star?
Blue stars are stars that have at least 3 times the mass of the Sun and up. Whether a star has 10 times the mass of the Sun or 150 solar masses, it’s going to appear blue to our eyes. An example of a blue star is the familiar Rigel, the brightest star in the constellation Orion and the 6th brightest star in the sky.
