Since the discovery of Kepler-10, the system has received considerableinterest because it contains a small, rocky planet which orbits the star inless than a day. The system's parameters, announced by the Kepler team andsubsequently used in further research, were based on only 5 months of data. Wehave reanalyzed this system using the full span of 29 months of Keplerphotometric data, and obtained improved information about its star and theplanets. A detailed asteroseismic analysis of the extended time series providesa significant improvement on the stellar parameters: Not only can we state thatKepler-10 is the oldest known rocky-planet-harboring system at 10.41 +/- 1.36Gyr, but these parameters combined with improved planetary parameters from newtransit fits gives us the radius of Kepler-10b to within just 125 km. A newanalysis of the full planetary phase curve leads to new estimates on theplanetary temperature and albedo, which remain degenerate in the Kepler band.Our modeling suggests that the flux level during the occultation is slightlylower than at the transit wings, which would imply that the nightside of thisplanet has a non-negligible temperature.
