Several other planets may have been detected in this system. However, they are unconfirmed and / or evidence of their existence is based solely on short term observations of anomalies in the asymmetric dust ring. Detection is made difficult due to the star's variable nature and because we are near the limit of current instruments
DUST RING:
AUs: stretches from 3 to 60 particle size in ring about 1mm
