Title:  ROTATION AND AGES OF SOLAR ANALOGS REVEALED BY THE KEPLER MISSION

Abstract:
We present a new sample of 70 solar-type field stars that potentially contain solar analogs and possibly even twins. We present stellar rotation periods and ages for this sample. By taking into account a control sample we analyze properties of new solar twins by using long-cadence data (Q0-Q16) to study their rotation. These were measured by detecting periodic photometric modulation caused by star spots. We included in the sample the evolved solar-type stars 16 Cyg A & B that represents a proxy to the future of our own Sun. Our study is particularly interesting to test how stellar sismo- and gyro- ages can be reliable in an dataset of a controlled set of stellar parameters.
