HD9446 radial velocity curve

Listed in IVOA Registry (Virtual Observatory)

We report the discovery of a planetary system around HD 9446, performed from radial velocity measurements secured with the spectrograph SOPHIE at the 193-cm telescope of the Haute-Provence Observatory for more than two years.

Description

At least two planets orbit this G5V, active star: HD 9446b has a minimum mass of 0.7M_Jup_ and a slightly eccentric orbit with a period of 30-days, whereas HD 9446c has a minimum mass of 1.8M_Jup_ and a circular orbit with a period of 193-days.

As for most of the known multiple planet systems, the HD 9446-system presents a hierarchical disposition with a massive outer planet and a lighter inner planet.
