28 Jan 2014: Based on dynamical considerations of orbital stability, Horner et al. (2014) cast doubt on the planet candidates NN Ser (AB) b and c.
13 Oct 2010: An alternate model with a similar chi^2 gives
Mc = 1.60 MJ, Pc = 6.69 yr and ac = 3.07 AU (Beuermann et al. 2010)
13 Oct 2010: For the planet designation, I follow the Beuermann et al. (2010) convention, NN Ser ab being, after the recommendation of the Editor of Astronomy and Astrophysics, the name of the parent binary star.
3 Nov. 2009: Given the O-C curve (Fig 2) of Qian et al 2009, the
planet is only marginally significant.
