Aims.We report the discovery of WASP-38b, a long period transiting planet in an eccentric 6.871815 day orbit. The transit epoch is 2 455 335.92050 ± 0.00074 (HJD) and the transit duration is 4.663 h. Methods.WASP-38b's discovery was enabled due to an upgrade to the SuperWASP-North cameras.We performed a spectral analysis of the host star HD 146389/BD+10 2980 that yielded Teff = 6150 ± 80 K, log g = 4.3 ± 0.1, v sin i = 8.6 ± 0.4 kms-1, M* = 1.16 ± 0.04 M⊙ and R* = 1.33 ± 0.03 R⊙, consistent...[Show more]
