We’re back, we’re tanned, we’re rested, we’re ready: 4th day, session 7,
in which Kepler annouces the discovery of the second circumbinary exoplanet…
Ok, we’re not going yet, but the press release came out at noon:
– 41d orbital period binary star, KV primary (bit less massive than the Sun).
Secondary is an M star.
Sub-solar metallicity, low eccentricity stellar orbit (e1=0.15)
about 60 pc away.
Planet is transiting, natch, 0.33 MJM
in a 229d near circular circumbinary orbit.
This is the second circumbinary planet discovered, after 1620-26b and the first orbiting two main sequence stars.
