HARPS-N reveals the Secrets of the Hot Neptune TOI-3862 b

Thanks to observations carried out with the high resolution spectrograph HARPS-N at the Telescopio Nazionale Galileo (TNG), astronomers have characterized the rare exoplanet named TOI-3862 b. The planet, with a radius of approximately 0.8 Jupiter radii and an unusually high density of ~ 1.7 g cm-3, resides in the so-called hot Neptune desert, a region where Neptune-sized planets are scarce despite their relative detectability.
