Afifth planet is presented, with an apparent orbital period of 260 days, placing it 0.78 AU from the star in the large empty zone between two other planets. The velocity wobble amplitude of 4.9 m s � 1 implies a minimum planet massM sini ¼ 45:7 M� . The orbital eccentricity is consistent with a circular orbit, but… CONTINUE READING
