We report the discovery by the WASP transit survey of two new highly irradiated giant planets .
WASP-64 b is slightly more massive ( 1.271 \pm 0.068 M _ { Jup } ) and larger ( 1.271 \pm 0.039 R _ { Jup } ) than Jupiter , and is in very-short ( a = 0.02648 \pm 0.00024 AU , P = 1.5732918 \pm 0.0000015 days ) circular orbit around a V =12.3 G7-type dwarf ( 1.004 \pm 0.028 M _ { \odot } , 1.058 \pm 0.025 R _ { \odot } , T _ { eff } = 5500 \pm 150 K ) .
Its size is typical of hot Jupiters with similar masses .
WASP-72 b has also a mass a bit higher than Jupiter ’ s ( 1.461 _ { -0.056 } ^ { +0.059 } M _ { Jup } ) and orbits very close ( 0.03708 \pm 0.00050 AU , P = 2.2167421 \pm 0.0000081 days ) to a bright ( V =9.6 ) and moderately evolved F7-type star ( 1.386 \pm 0.055 M _ { \odot } , 1.98 \pm 0.24 R _ { \odot } , T _ { eff } = 6250 \pm 100 K ) .
Despite its extreme irradiation ( \sim 5.5 \times 10 ^ { 9 } erg s ^ { -1 } cm ^ { -2 } ) , WASP-72 b has a moderate size ( 1.27 \pm 0.20 R _ { Jup } ) that could suggest a significant enrichment in heavy elements .
Nevertheless , the errors on its physical parameters are still too high to draw any strong inference on its internal structure or its possible peculiarity .
