FEROS spectra for 3 giants exoplanets

We report the discovery and characterization of three giant exoplanets orbiting solar-analog stars, detected by the TESS space mission and confirmed through ground-based photometry and radial velocity measurements taken at La Silla observatory with FEROS. TOI-2373b is a warm Jupiter orbiting its host star every ~13.3days, and is one of the most massive known exoplanet with a precisely determined mass and radius around a star similar to the Sun, with an estimated mass of mp=9.3_-0.2_^+0.2^Mjup and a radius of rp=0.93_-0.2_^+0.2^Rjup. With a mean density of {rho}=14.4_-1.0_^+0.9^g/cm^3^, TOI-2373b is among the densest planets discovered so far. TOI-2416b orbits its host star on a moderately eccentric orbit with a period of ~8.3days and an eccentricity of e=0.32_-0.02_^+0.02^. TOI-2416 bis more massive than Jupiter with mp=3.0_-0.09_^+0.10^Mjup, however is significantly smaller with a radius of rp=0.88_-0.02_^+0.02^Rjup, leading to a high mean density of {rho}=5.4_-0.3_^+0.3^g/cm^3^. TOI-2524b is a warm Jupiter near the hot Jupiter transition region, orbiting its star every ~7.2days on a circular orbit. It is less massive than Jupiter with a mass of mp=0.64_-0.04_^+0.04^Mjup, and is consistent with an inflated radius of rp=1.00_-0.03_^+0.02^Rjup, leading to a low mean density of {rho}=0.79_-0.08_^+0.08^g/cm^3^. The newly discovered exoplanets TOI-2373b, TOI-2416b, and TOI-2524b have estimated equilibrium temperatures of 860_-10_^+10^K, 1080_-10_^+10^K, and 1100_-20_^+20^K, respectively, placing them in the sparsely populated transition zone between hot and warm Jupiters.
