2M1938+4603 (AB)b - Circumbinary planet in a sdB+M dwarf system

At first I could not believe but there was free access to this: Suspect  What a Face

A circumbinary planet orbiting a sdB+M system in Kepler's field.

Detection of a planet in the sdB + M dwarf binary system 2M1938+4603


We analyze 37 months of Kepler photometry of 2M1938+4603, a binary system with a pulsating hot subdwarf primary and an Mdwarf
companion that shows strong reflection effects.We measured the eclipse timings from more than 16 000 primary and secondary
eclipses and discovered a periodic variation in the timing signal that we ascribe to a third body in the system. We also discovered a
significant long-term trend that may be an evolutionary effect or a hint of more bodies. Upon the assumption that the third body is
orbiting in the same plane as the primary, we establish that it must be a Jupiter-mass object orbiting with a period of 416 days at a
distance of 0.92AU. This mass is the lowest among all tertiary components detected in similar systems.
