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, M-star = 0.96 M-circle dot, R-star = 0.89 R-circle dot, T-eff approximate to 5500 K, [Fe/H] = 0.05; HATS-14: V = 13.8 mag, M-star = 0.97 M-circle dot, R-star = 0.93 R-circle dot, T-eff approximate to 5350 K, [Fe/H] = 0.33) and both the planets orbit around them with a period of similar to 3 days and a separation of similar to 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 M-p = 0.543 +/- 0.072 M-J and a radius of R-p = 1.212 +/- 0.035 R-J, appears as an inflated planet, while HATS-14b, having a mass of M-p = 1.071 +/- 0.070 M-J and a radius of R-p = 1.039 +/- 0.032 R-J, is only slightly larger in radius than Jupiter. |
