Correlation diagrams for confirmed transit planets (exoplanet.eu, last updated January 10, 2013). From top to bottom: planetary radius R_p vs. stellar radius R_⋆, planetary mass M_P vs. planetary equilibrium temperature T_eq,P, planetary radius R_p vs. planetary equilibrium temperature T_eq,P, planetary radius R_p vs. stellar effective temperature T_eff, ⋆ and planetary radius R_p vs. planetary mass M_P. The positions of the HATS-2 and HATS-2b parameters are marked in red squares. Left panels give a general overview of the position of HATS-2 and HATS-2b in the population of known transit planets (black filled circles). Right panels illustrate a zoom-in; green diamonds represent known exoplanets that fall within the errorbars of the HATS-2 system parameters. Short cuts: HP = HAT-P, W = WASP, T = TrES.
