| A study of γ Cephei, using the inclination and ascending node from Reffert & Quirrenbach (2011) - i.e. Hipparcos intermediate astrometric data, rather than the FGS results of Benedict et al. (2018), but doing a new N-body fit to the data assuming the inclination from the astrometry. Appears to favour higher masses for γ Cep Ab ~15 Jupiter masses.
