(Phys.org)—V1331 Cygni is a young variable star that lies in the constellation Cygnus, approximately 1,800 light years away from our planet. The star is known to have a circumstellar disk surrounded by a flattened gaseous envelope that could reveal crucial information on V1331 Cygni's violent past. A recent study of the motion of these circumstellar structures shows that this star must have undergone an outburst a few thousand years ago. The results appeared in a paper published online on Apr. 15 in the arXiv journal.
