## 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<inf>z.ast;</inf> = 0.96 M<inf>⊙</inf>, R<inf>z.ast;</inf> = 0.89 R<inf>⊙</inf>, T<inf>eff</inf> ≈ 5500 K, [Fe/H] = 0.05; HATS-14: V = 13.8 mag, M<inf>z.ast;</inf> = 0.97 M<inf>⊙</inf>, R<inf>z.ast;</inf> = 0.93 R<inf>⊙</inf>, T<inf>eff</inf> ≈ 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 M<inf>p</inf> = 0.543 ± 0.072 M<inf>J</inf> and a radius of R<inf>p</inf> = 1.212 ± 0.035 R<inf>J</inf>, appears as an inflated planet, while HATS-14b, having a mass of M<inf>p</inf> = 1.071 ± 0.070 M<inf>J</inf> and a radius of R<inf>p</inf> = 1.039 ± 0.032 R<inf>J</inf>, is only slightly larger in radius than Jupiter.
