In 2005, Jack Wisdom combined three data sets and drew two distinct conclusions: that the 2.8 day planet was an alias and that there was a Neptune-scale planet with a period near 261 days. Fischer et al. (2008) reported new observations that they said confirmed the existence of the 2.8 day planet, as first reported by McArthur et al. (2004), and a 260-day Neptune-sized planet, as first reported by Wisdom (2005). However, Dawson and Fabrycky (2010) concluded that the 2.8 day planet was indeed an alias, as suggested by Wisdom (2005), and that the correct period was 0.7365 days.
