Habitable-zone super-Earth candidate in a six-planet system around the K2.5V star HD 40307

Mikko Tuomi, Guillem Anglada-Escude, Enrico Gerlach +5

The K2.5 dwarf HD 40307 has been reported to host three super-Earths. The system lacks massive planets and is therefore a potential candidate for having additional low-mass planeta…
