  • We report on a V = 11.2 early K dwarf, XO-2 (GSC 03413-00005), that hosts a Rp = 0.98±0.010.03 RJ, Mp = 0.57 ± 0.06 MJ transiting extrasolar planet, XO-2b, with an orbital period of 2.615857 ± 0.000005 days. XO-2 has high metallicity, [Fe/H ] = 0.45 ± 0.02, high proper motion, μtot = 157 mas yr−1, and a common proper motion stellar companion with 31'' separation. The two stars are nearly identical twins, with very similar spectra and apparent magnitudes. Due to the high metallicity, these early… CONTINUE READING
