The orbital period of the SU Ursae Majoris star AK Cancri *
Received 9 March 1998 / Accepted 23 June 1998
A time resolved spectroscopic study of the SU UMa subtype dwarf nova AK Cancri is presented. An orbital period of and a radial velocity half-amplitude of 50(3) km s-1 were obtained from the radial velocity variations of the H emission line. Assuming various observational constraints, we deduced a most likely mass ratio of and stellar masses of and , for the primary and secondary star, respectively. In addition, the dynamical solution indicates a low orbital inclination ().
