Has This New Discovered Planet Suddenly Disappeared?

Located in the constellation of Piscis Austrinus -the southern fish- Fomalhaut is one of the brightest stars in the sky.
It is a class A star, therefore is quite hot, and its distance from the sun accounts for about 25 light-years, as measured by the fantastic Hipparcos mission.

Fomalhaut is a special star for many reasons.
For example, it was used as a stable anchor point for star classification: its beautiful spectrum has served as a calibration spectrum for all the other stars.
It is, in fact, a Vega-like star, surrounded by the circumstellar disk, which results in an infrared excess of radiation. This means that Fomalhaut it’s quite reddish.

Alpha Piscis Austrini, as Fomalhaut is also called, it’s not alone: it constitutes a triple star system along with the stars TW Piscis Austrini and LP 876-10.

But what makes Fomalhaut even more special?
