25 May 2014: The planet HD 41248 c has been challenged by Santos et al. (2014).
August 2017: Feng et al (2017) say that the 26 d signal (HD 41248 c announced by Jenkins et al. 2013) is probably caused by a combination of planetary perturbation and stellar rotation while the 18.4 d signal (HD 41248 b announced by Jenkins et al. 2013) is not significant and is an alias of the 13.4 d signal.
