The Librating Companions in HD 37124, HD 12661, HD 82943, 47 Uma and GJ 876: Alignment or Antialignment?

Jianghui Ji, Lin Liu, H. Kinoshita +3

We investigated the apsidal motion for the multi-planet systems. In the simulations, we found that the two planets of HD 37124, HD 12661, 47 Uma and HD 82943 separately undergo aps…

Could the 55 Cancri Planetary System Really Be in the 3:1 Mean Motion Resonance?

Ji Jianghui, H. Kinoshita, Liu Lin +1

We integrate the orbital solutions of the planets orbiting 55 Cnc. In the simulations, we find that not only three resonant arguments , $θ_{2}=λ_{1…
