WASP-38b is a recently by Barros et al. (2010) discovered planet around a F8 main sequence star showing a nonzero eccentricity. Radial velocity follow-up observations show that there are some points that cannot be explained by a strictly Keplerian orbit, making WASP-38 an interesting case to look for variations.
