In 2008 Grinin et al. invoke the possible presence of a substellar object to explain peculiar and periodic eclipses occurring to the young star every 4.7 years.
The presence of a planetary object is still invoked in a recent research.
They infer a maximum mass of 6 times that of
Jupiter for the perturbing object and an orbital separation of 3.3
astronomical units.
