CVSO 30 is a star, located in constellation Orion at 1200 light years from Earth away with two candidate planets (CVSO 30 b and CVSO 30 c). It is the first star around which potential planets have been found both by the transit method and by direct imaging.
CVSO 30 b is calculated to have a period of 10.76 hours (0.008 AU) and CVSO 30 c a period of 27,000 years (660 AU).[3] [4]
Direct imaging of CVSO 30 c has been achieved through photometric and spectroscopic high contrast observations carried out with the Very Large Telescope located in Chile, the Keck Observatory in Hawaii and the Calar Alto Observatory in Spain. Both candidate planets are gas giants.[5]
