Abstract

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, Mz.ast; = 0.96 M, Rz.ast; = 0.89 R, Teff ≈ 5500 K, [Fe/H] = 0.05; HATS-14: V = 13.8 mag, Mz.ast; = 0.97 M, Rz.ast; = 0.93 R, Teff ≈ 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.
