The Disc Miner

[Abridged] The study of disc kinematics has recently opened up as a promising method to detect unseen planets. However, systematic, statistically meaningful analysis such an approach remains missing. aim this work is devise automated, robust technique identify kinematical perturbations induced by the presence planets in gas disc, and accurately infer their location. For purpose, we produce hydro simulations planet-disc interactions with different planet masses, 0.3, 1.0 3.0 $M_{Jup}$, at radius $R=100$ au perform radiative transfer calculations CO simulate observables for 13 azimuths. Using DISCMINER package, fit synthetic data cubes Keplerian model channel-by-channel emission line profile differences, including deviations from rotation. detection technique, based on centroid captures localised planet-driven perturbations, can distinguish them axisymmetric velocity perturbations. all three simulated planets, azimuths, average accuracy $\pm3^\circ$ azimuth $\pm8$ radius. Owing structure line-of-sight projection effects, azimuths close $\pm45^\circ$ yield highest fluctuations, whereas those limiting cases, $0^\circ$ $\pm90^\circ$, drive lowest. observed peak velocities range within 40$-$70, 70$-$170 130$-$450 m s$^{-1}$ $M_{Jup}$ Our indicates that variance boosted near due organised motions prompted gravitational well. We propose exploits coherence provide, first time, significant detections kinematics.
