Both stars are close to our sun in size. The visible area in square-arc-seconds (and thus the brightness) of Beta as seen from Alpha (and vice versa) should be about (1/11)^2 = 0.8 % or about the same as an overcast day on Earth. I think I read that stable planet orbits would be impossible, but I suppose a planet could still have a stable orbit around one of the Lagrange points. Then it should have each star at equal distance, at 90 deg angle, right? If so, it would have 4 phases of daylight - night, Alpha, both suns and Beta.
