Abstract / Description:We report the discovery of HATS-13b and HATS-14b, which are two hot-Jupiter transiting planets discovered by the HATSouth survey. The host stars are quite similar to each other (HATS-13: V = 13.9 mag, M* = 0.96 M&sun;, R* = 0.89 R&sun;, Teff &ap; 5500 K, [Fe/H] = 0.05; HATS-14: V = 13.8 mag, M* = 0.97 M&sun;, R* = 0.93 R&sun;, Teff &ap; 5350 K, [Fe/H] = 0.33) and both the planets orbit around them with a period of ~3 days and a separation of ~0.04 au. However, even though they are irradiated in a similar way, the physical characteristics of the two planets are very different. HATS-13b, with a mass of Mp = 0.543 ± 0.072 MJ and a radius of Rp = 1.212 ± 0.035 RJ, appears as an inflated planet, while HATS-14b, having a mass of Mp = 1.071 ± 0.070 MJ and a radius of Rp = 1.039 ± 0.032 RJ, is only slightly larger in radius than Jupiter. The HATSouth network is operated by a collaboration consisting of Princeton University (PU), the Max Planck Institute für Astronomie (MPIA), the Australian National University (ANU), and the Pontificia Universidad Católica de Chile (PUC). The station at Las Campanas Observatory (LCO) of the Carnegie Institute is operated by PU in conjunction with PUC, the station at the High Energy Spectroscopic Survey (HESS) site is operated in conjunction with MPIA, and the station at Siding Spring Observatory (SSO) is operated jointly with ANU. Based in part on observations made with (i) the Subaru Telescope, which is operated by the National Astronomical Observatory of Japan; (ii) the MPG 2.2 m and the (iii) Euler 1.2 m Telescopes at the ESO Observatory in La Silla; (iv) the CTIO 0.9 m Telescope at the Observatory of Cerro Tololo.Appendix A is available in electronic form at <A href=""></A>Full Table A.1 and RV Tables are only available at the CDS via anonymous ftp to <A href=""></A> ( or via <A href=""></A>
