Scientific paper

An analysis of the minimum-time data of AK Her and ER Ori reveals possible sinusoidal variations in their orbital periods. In the case of AK Her the authors suspect two additional components: one of mass 0.2 to 0.4 M_sun; with a period of 62 yr and the other of mass 0.2 to 0.6 M_sun; with a period of 207 yr. The probable third mass in ER Ori is less than 0.6 M_sun; for i ≥ 60° with a long-term period of 34.78 yr.
