Supplementary Materials

This PDF file includes:

  • Fig. S1. Stacked BGLS periodograms for subsets of RV residuals.
  • Fig. S2. Posterior distributions of parameters and hyperparameters relative to an MC exploratory run where the global model is composed of a GP quasi-periodic kernel and two planetary orbital equations, with eccentricities treated as free parameters.
  • Fig. S3. Posterior distributions for all the free parameters of the model adopted in this work, which includes a GP quasi-periodic kernel to fit the stellar activity term in the RV, and two circular orbital equations (see Table 1).
  • Fig. S4. Stellar activity signal as found in the RV through a GP regression using a quasi-periodic kernel.
  • Fig. S5. Analysis of Ha activity index.
  • Fig. S6. Minimum mass versus orbital semi-major axis of confirmed planets orbiting low-mass stars (M < 0:6 M) discovered with the RV technique.
  • Table S1. Other models used for fitting the RVs, as discussed in the text.
