cds-question@unistra.frmultiple-starsexoplanetsradial-velocityvisible-astronomyThe Rocky Planet Search (RPS) program is dedicated to a blind radial velocity (RV) search of planets around bright stars in the Northern hemisphere, using the high-resolution echelle spectrograph HARPS-N installed on the Telescopio Nazionale Galileo (TNG). The goal of this work is to revise and update the properties of three planetary systems by analysing the HARPS-N data with state-of-the-art stellar activity mitigation tools. The stars considered are HD 99492 (83 Leo B), HD 147379 (Gl617 A) and HD 190007. Methods. We employ a systematic process of data modelling, that we selected from the comparison of different approaches. We use YARARA to remove instrumental systematics from the RV, and then use SPLEAF to further mitigate the stellar noise with a multidimensional correlated noise model. We also search for transit features in the Transiting Exoplanets Survey Satellite (TESS) data of these stars. We report on the discovery of a new planet around HD99492, namely HD99492 c, with an orbital period of 95.2 days and a minimum mass of msini=17.9M_{Earth}_, and refine the parameters of HD99492 b. We also update and refine the Keplerian solutions for the planets around HD 147379 and HD 190007, but do not detect additional planetary signals. We discard the transiting geometry for the planets, but stress that TESS did not exhaustively cover all the orbital phases. The addition of the HARPS-N data, and the use of advanced data analysis tools, has allowed us to present a more precise view of these three planetary systems. It demonstrates once again the importance of long observational efforts such as the RPS program. Added to the RV exoplanet sample, these planets populate two apparently distinct populations revealed by a bimodality in the planets' minimum mass distribution. The separation is located between 30 and 50M_{Earth}_.2023A&A...678A..90Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/678/A90CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/678/A90https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/678/A90http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/678/A90https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/678/A90https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/678/A90http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/678/A90GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/678/A90/hd99492HD 99492 radial velocity measurementsrecnoRecord number assigned by the VizieR team.
