Could there be an undetected inner planet near the stability limit in Kepler-1647?   Abstract: Kepler-1647b  is  the  most  recently  discovered  planet  that  transits  two  stars,  e.g.,  a  circumbinary planet (CBP). Due to its large orbital separation, Kepler-1647b stands out from the rest of the Kepler CBPs, which mostly reside on much tighter orbits near … Continue reading "CRA Cosmic Coffee: Ziqian Hong"
