| Exoplanetary Scratchpad |
A star with a massive dust disk that disappeared overnight, which has not been observed in any other star. A young solar analog star 450 ly in Centaurus. The disk was first observed in 1983, started to dim in 2009, and emissions from the disk were completely gone by 2010 and confirmed as still gone in 2012. The dust probably appeared as a result of a collision, but the reason for its disappearance is unknown (there appears to be no stellar activity that would have destroyed the disk). The disk had extended from the star to a Mercury-like orbit. Planets are likely forming in the system, and the formation of a rocky planet could be responsible.
