White Dwarf Photospheric Abundances in Cataclysmic Variables. III. Five Dwarf Novae with an Evolved Secondary Donor Star
In the last two decades infrared spectroscopy has brought mounting evidence, in the form of weak CO features together with enhanced ^13 C, of the presence of CNO-processed material in the atmosphere of the donor star of some nonmagnetic cataclysmic variables. Some of these donors also exhibit a temp...
