Description
In paper 167 of his serie published in The Observatory, Griffin presented the spectroscopic orbit of HD 112914, a late main sequence star. He also noticed that this star, also known as HIP 63406, was one of the few for which the DMSA/O Annex of the Hipparcos Catalogue derived an orbit prior to any spectroscopic one. Albeit in agreement with each others, the astrometric orbit was however determined with rather large uncertainties. Here, we have reanalysed the Hipparcos Intermediate Astrometric Data (IAD) using Griffin'spectroscopic orbit to obtain a much more precise astrometric orbit. Several parameters of the HD 112914 system are now well constrained.
