  • "The CORALIE survey for southern extra-solar planets. XII. Orbital solutions for 16 extra-solar planets detected with CORALIE"
    M. Mayor, S. Udry, D. Naef, F. Pepe, D. Queloz, N.C. Santos, M. Burnet, 2004
    A&A 415, 391 (ADS)
  • A secondary 30-d signal was detected in the 2000 velocity data. This signal has vanished. Its origin remains unknown.
  • Announcement: ESO Press Release 13/00

    • Top: Phase-folded velocities and orbital solution
    Bottom: Residuals around the solution
    Fourier transform of the residuals around the 2.98-d solution.
    Top: Velocities taken between JD=51500 and JD=51702 when
    the 30-d signal was seen in the data. The false alarm
    probability of this signal is 0.09%.
    Bottom: the same for later velocities
