Orbital properties of an unusually low-mass sdB star in a close binary system with a white dwarf
Orbital properties of an unusually low-mass sdB star in a close binary system with a white dwarf
We have used 605 days of photometric data from the Kepler spacecraft to study KIC 6614501, a close binary system with an orbital period of 0.15749747(25) days (3.779939 hours), that consists of a low-mass subdwarf B (sdB) star and a white dwarf. As seen in many other similar systems, the …
