THE RØMER DELAY AND MASS RATIO OF THE sdB+dM BINARY 2M 1938+4603 FROM<i>KEPLER</i>ECLIPSE TIMINGS
The eclipsing binary system 2M 1938+4603 consists of a pulsating hot subdwarf B star and a cool M dwarf companion in an effectively circular three-hour orbit. The light curve shows both primary and secondary eclipses, along with a strong reflection effect from the cool companion. Here we present constraints on …
