  • We examine eight known single-eccentric planetary systems in light of recently released large data archives and new analysis techniques. For four of these systems (HD 7449, HD 65216, HD 89744, HD 92788) we find evidence for additional long-period companions. HD 65216c is a Jupiter analogue, with a period of 14.7 yr, e = 0.18, and m sin i of 2MJup, while the remaining candidate companions move on as- yet-incomplete orbits. Our results highlight the importance of revisiting the analysis of known… CONTINUE READING
