Abstract

Through photometric monitoring of the extended transit window of HD 97658b with the MOST space telescope, we have found that this exoplanet transits with an ephemeris consistent with that predicted from radial velocity measurements. The mid-transit times are 5.6 σ earlier than those of the unverified transit-like signals reported in 2011, and we find no connection between the two sets of events. The transit depth together with our determined stellar radius ($ R_\ star= 0.703^+ 0.039 _ -0.034\ R_\ odot $) indicates a 2.34$^+ 0.18 ...
