so I am a little confused. I thought Fomalhaut was a small galaxy with numerous stars example Fomalhaut A , Fomalhaut B  etc. Now the article states that Fomalhaut B disappeared but does not give information about Fomalhaut A and the other stars and exoplanets in Fomalhaut.  So are those still there or did all of Fomalhaut disappear? And yes I know they think what they saw was a dust cloud

Formalhaut is a star.

Formalhaut b was thought to be a planet orbiting that star.

Now they think it perhaps was the remains of a collision between two large bodies orbiting Formalhaut.

A final point of clarification:

• Fomalhaut A and B are stars.
• Fomalhaut a and b are planets. (Well, b is apparently not a planet.)
• The article is about Fomalhaut b "disappearing" (not being a planet in the first place). Fomalhaut B is still there.
