Resumen

We present the discovery of K2-113, a dense hot-Jupiter discovered using photometry from Campaign 8 of theKepler-2 (K2) mission and high-resolution spectroscopic follow-up obtained with the FEROS spectrograph. The planet orbits a V = 13.68 solar analogue in a P = 5.817 60_{-0.000 03}^{+0.000 03} d orbit, and has a radius of 0.93+0.10-0.07RJ and a mass of 1.29_-0.14^+0.13 MJ. With a density of 1.97_-0.53^+0.60 g cm^-3, the planet is among the densest systems known having masses below 2 M_J and T_eq > 1000, and is just above the temperature limit at which inflation mechanisms are believed to start being important. Based on its mass and radius, we estimate that K2-113 should have a heavy element content of the order of ~110 M⊕ or greater.
