17 Nov 2015: The names an characteristics of planets HD 219134 d, e, f, g and h raise two specific problems since there are two papers: Motalebi et al. 2015 and Vogt et al. 2015 with different sets of parameters. We adopt the following solution, at least provisionally:
- names: The standard rule is two give names NNN b, c, d etc by order of discovery, the criterion being the date of submission of a paper. The Motalebi et al paper has been submitted on June 24th 2015, the Vogt et al. paper on July 17th 2015. The four Motalebi planets are there fore named b, c, d and e and the new Vogt planets named f, g and h.
- parameter values: The Vogt et al. planet data are based on 276 observation points while the Motalebi et al data are based on 98 data points. We therefore adopt Vogt et al. values for all planet.
- remark: It is not impossible that more data will change this situation. In particular HD 219134 e and h may merge in a single object.
