cds-question@unistra.frexoplanetshigh-velocity-starsvisible-astronomyspectroscopyradial-velocityThousands of exoplanet detections have been made over the last 25 years using Doppler observations, transit photometry, direct imaging, and astrometry. Each of these methods is sensitive to different ranges of orbital separations and planetary radii (or masses). This makes it difficult to fully characterize exoplanet architectures and to place our solar system in context with the wealth of discoveries that have been made. Here, we use the EXtreme PREcision Spectrograph to reveal planets in previously undetectable regions of the mass- period parameter space for the star {rho} Coronae Borealis. We add two new planets to the previously known system with one hot Jupiter in a 39day orbit and a warm super-Neptune in a 102day orbit. The new detections include a temperate Neptune planet (Msini~20M{Earth}) in a 281.4day orbit and a hot super-Earth (Msini=3.7M{Earth}) in a 12.95day orbit. This result shows that details of planetary system architectures have been hiding just below our previous detection limits; this signals an exciting era for the next generation of extreme precision spectrographs.2023AJ....166...46Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/166/46CatalogResearchIsServedByTAP VizieR generic servicerelated-toIII/185 : Search for Jupiter-Mass Companions (Walker+, 1995)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)J/ApJ/457/L99 : 25yr CaII-HK observations of FK nearby stars (Baliunas+, 1996)J/ApJ/622/1102 : The planet-metallicity correlation.
