2015 : The (O-C) may be also driven by oscillations of the gravitational quadrupole moment of the secondary, as predicted by the Lanza et al. modification of the Applegate mechanism. Gozdziewski et al. (2015),
21 May 2012: A previous orbital solution for the timing variations of the eclipses of HU Aqr(AB) led to two planets (Qian et al. 2011). A re-analysis by Gozdziewski et al. (2012), based on new data concludes that a better fit is obtained by a single circumbinary planet, here designated as HU Aqr(AB)b.
02 Dec 2011: Planet validated by new data fitting (Hinse et al. 2012)
13 Oct 2011: The planet parameters result from one of the models by Wittenmyer et al. (2011). According to these authors, "the improved orbital parameters
correspond to planets that are dynamically unstable on unfeasibly short timescales
(of order 104 years or less). Given these results, the observed
signal might in fact be the result of the intrinsic properties of the eclipsing polar".
