TEPCat: Kepler-47c


 

This page summarises the information held within TEPCat for the transiting planetary system Kepler-47c. Please see here for descriptions of the quantities given below.

This object consists of an eclipsing binary star system which is itself eclipsed by one or more transiting planets. The binarity of the central star causes problems for structured databases. The stellar data below refer specifically to the primary star, and the planetary data to the transiting planet. For further information on the secondary star or the system as a whole please consult the publication(s) referenced below.
