TOI-5076b flux and velocity curves

We report the confirmation of a new transiting exoplanet orbiting the star TOI-5076.
Description
We present our vetting procedure and follow-up observations which led to the confirmation of the exoplanet TOI-5076b. In particular, we employed high-precision TESS photometry, high-angular-resolution imaging from several telescopes, and high-precision radial velocities from HARPS-N. From the HARPS-N spectroscopy, we determined the spectroscopic parameters of the host star: Teff=(5070+/-143)K, logg=(4.6+/-0.3), [Fe/H]=(+0.20+/-0.08), and [alpha/Fe]=0.05+/-0.06.
The transiting planet is a warm sub-Neptune with a mass mp=(16+/-2)M_{Earth}_, a radius rp=(3.2+/-0.l)R_{Earth}_ yielding a density {rho}p=(2.8+/-0.5)g/cm^3^. It revolves around its star approximately every 23.445 days. The host star is a metal-rich, K2V dwarf, located at about 82 pc from the Sun with a radius of R*=(0.78+/-0.01)R_{sun}_ and a mass of M*=(0.80+/-0.07)M_{sun}_.

It forms a common proper motion pair with an M-dwarf companion star located at a projected separation of 2178au. The chemical analysis of the host-star and the Galactic-space velocities indicate that TOI-5076 belongs to the old population of thin-to-thick-disk transition stars. The density of TOI-5076b suggests the presence of a large fraction by volume of volatiles overlying a massive core.
We found that a circular orbit solution is marginally favored with respect to an eccentric orbit solution for TOI-5076b.
