abstract
The radial-velocity (RV) method is one of the most successful in the detection of exoplanets, but is hindered by the intrinsic RV variations of the star, which can easily mimic or hide true planetary signals. kima is a package for the detection and characterization of exoplanets using RV data. It fits a sum of Keplerian curves to a timeseries of RV measurements and calculates the evidence for models with a fixed number Np of Keplerian signals, or after marginalising over Np. Moreover, kima can use a GP with a quasi-periodic kernel as a noise model, to deal with activity-induced signals. The hyperparameters of the GP are inferred together with the orbital parameters. The code is written in C++, but includes a helper Python package, pykima, which facilitates the analysis of the results.

Interpolation algorithm choice in template-based RV extraction from high-resolution spectra introduces systematic biases reaching 20-25 m/s in low-SNR cases and under 0.2 m/s when BERV variation is large, demonstrated via Gaussian synthetic spectra and ESPRESSO observations.
Three massive planets detected around HD125136 (2.26 MJup, 850 d) and HD127195 (0.66 and 0.78 MJup, 535 d and 834 d) via Bayesian Keplerian modeling of CORALIE RV series; one additional signal attributed to activity.
Three new hot Jupiters (periods 1.8-4 days, radii 1.22-1.58 RJup, masses 0.36-0.87 MJup) around evolved stars aged 4-9 Gyr, extending the sample for hot Jupiter evolutionary studies.
