Remarks

09 Feb 2011: The candidate DQ Her(ab)c is suggested by Dai & Qian (2009) as a plausible explanation of the periodic variations of the eclipses of DQ Her(ab). The mass value is given by assuming that the 3rd body orbit is coplanar with the DQ Her(ab) orbit inclined by 86.5 deg.

Remarks

09 Feb 2011: DQ Her (ab) is an eclipsing binary with masses 0.4 and 0.8 mSun and period 4h39m. (Dai & Qian 2009). Following Beuermann et al. (2010) for the designation of the binary NN ser, we designated the two components by a and b and the binary by (ab).
