Abstract

Context.The star γ Cep is known as a single-lined spectroscopic triple system at a distance of 13.8 pc, composed of a K1 III–IV primary star with mag, a stellar-mass companion in a 66–67 year orbit (Torres 2007, ApJ, 654, 1095), and a substellar companion with MJup that is most likely a planet (Hatzes et al. 2003, ApJ, 599, 1383).
