Superhumps in the helium dwarf nova KL Draconis.

WOOD M.A., CASEY M.J., GARNAVICH P.M. and HAAG B.

Abstract (from CDS):

We report on the discovery of a 25.5-min superhump period for the suspected helium dwarf nova system KL Draconis in a high state. The presence of superhumps combined with the previously observed helium spectrum and large-amplitude photometric variations confirm that KL Dra is an AM CVn system similar to CR Bootis, V803 Cen and CP Eridani. We also find a low-state photometric period at 25.0min that we suggest may be the orbital period. With this assumption, we estimate q =0.075, M1=0.76M☉ and M2=0.057M☉
