Remarks

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 = 5.92 MJ, Pc = 16.73 yr and ac = 5.66 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.
