Five Dwarf Novae with Orbital Periods below Two Hours
Five Dwarf Novae with Orbital Periods below Two Hours
We give mean spectra and report orbital periods Porb based on radial velocities taken near minimum light for five dwarf novae, all of which prove to have Porb<2 hr. The stars and their periods are KX Aql, 0.06035(3) day; FT Cam, 0.07492(8) day; PU CMa, 0.05669(4) day; V660 Her, 0.07826(8) …
