BD +20307

The yellow star is slightly bigger as our Sun. Around it is the most dusty environment ever found. The star, which isn't very young any more, probably has already formed a planetary system. Less than 1000 years ago there occured a crash between two large chunks of rock or even planets in about 1 AU distance of the star. The dust is the consequence of this crash.
