6 planets announced by the Yale Exoplanet Group

The Yale Exoplanet Group recently announced 6 planets that were previously unknown, 5 of which were in multi-planet systems. The inner planet in one of these systems, HD 163607b, is the most eccentric planet in any multi-planet system detected to date, which has interesting implications for the physical mechanisms under which planetary systems evolve. These discoveries also helped Yale astronomers determine that more than half of the smaller planets, so-called Super-Earths, are members of multi-planet systems like our own solar system...
