Piscis Austrinus means "southern fish." Or maybe "fish that speaks Austrian."
About Fomalhaut. It also has a dusk disk around it and may have a planet system forming.
It also may have two widely spaced companion stars, on is TWPsA a variable star almost 1 light year away. The other suspect is almost 2.5 light years away, but, seems to also be bound with Famalhaut.
More study is needed.
