The nature of dwarf Cepheids. V. Analysis and conclusions.
Abstract
The various observational arguments that can be or have been used to determine the nature of dwarf Cepheids are examined. Three evolutionary hypotheses are outlined and shown to lead to different expected period changes. Despite careful analysis, the derived period changes do not provide definite information on the evolutionary stage of most of the stars examined. Evidence for the Population I nature of most dwarf Cepheids (which are normal delta Scuti stars with large amplitudes) is presented.
