29 Aug 2024 Zervas & Christopoulou (2024) have an alternate set of values for the planet Msin i, period, eccentricity and omega (their tables 4 and 5)
20 Jan 2017 :
According to new data by Nasiroglu et al (2017), the planet NSVS 1425 (AB) d replaces the unconfirmed planets NSVS 1425 (AB) b and c. We provisionnaly name it NSVS 1425 (AB) d.
The candidate designated by "c" in Almeida et al. (2012) is designated here as "b", according to the homogeneity convention proposed by Schneider et al; (2012).

19 Feb 2012:
A planetary system with the orbital parameter given by Almeida et al. (2012) would be unstable (Wittenmyer et al). More observations are needed.
28 Feb 2012:
Beuermann et al. (2012) see a secondary eclipse at phase 0.5002 ± 0.0002.
