FOMALHAUT

THE STAR FORMATION

Formation: Generally every star goes through this stage

Main Sequence: In this stage right now

Giant: It will become a Red Giant

Dwarf/Neutron/Black Dwarf: It will be a White Dwarf then Turn into a Black Dwarf


Stars are formed inside molecular clouds. These regions are usually very cold, almost 10 to 20k just above absolute zero. At these temperatures, gases become molecular meaning that atoms bind together. Stars then turn into Main Sequence stars, which is what the Fomalhaut Star is right now. In billions of years, the Fomalhaut could turn into a Red Giant, then a White Dwarf, and eventually it will become a Black Dwarf.

HOW DO WE KNOW ABOUT IT?

In 2008, scientists announced a visible planet for Fomalhaut. It was the first extrasolar planet visible to the human eye in photographic images. We knew there were other planets out there, orbiting distant suns, when astronomers made this announcement in 2008. But, before the images of Fomalhaut B, all extrasolar planets made there presence known indirectly. For example, some made their presence known by their gravitational pull, tugging on their stars.

THE LONELIEST STAR?

The Fomalhaut Star is sometimes referred to as the Loneliest Star. The Fomalhaut Star is referred to as the Loneliest Star because it is the only bright star in it's region of the sky. It is most famous for it's planet, Fomalhaut B. Fomalhaut B was the first beyond our solar system to be visible to the human eye.
