Exoplanets
An exoplanet of this star, CVSO 30b , could already be detected using the radial velocity method in 2012 . In 2016, a team led by Tobias Schmidt from the University of Hamburg was able to use observation a. a. With the Very Large Telescope (VLT) another exoplanet can be detected by direct observation at a distance of 660 AU from the central star. This takes 27,000 years to complete one cycle, while CVSO 30b only takes 11 hours. The exoplanet CSVO 30c is currently (2018) controversial.
