Discovery of a multi-planetary system orbiting the aged Sun-like star HD 224018

M. Damasso, L. Naponiello, A. Anna John +22

In 2016, Kepler/K2 detected a system of two sub-Neptunes transiting the star HD 224018, one of them showing a mono-transit event. In 2017, we began a spectroscopic follow-up with H…
