Evolutionary status of dwarf Cepheids
Description
The high-mass (2M/sub solar mass/) and low-mass (0.5M/sub solar mass/) hypotheses are considered for Dwarf Cepheids, by examining the periods, abundances, radii, space motions, pulsation modes and the period-gravity relation. The vast majority of Dwarf Cepheids appear to be high-mass stars and resemble delta Scuti stars. It is proposed that the artificial distinction between Dwarf Cepheids and delta Scuti stars be abolished. Only a few Dwarf Cepheids are consistently different from the other Dwarf Cepheids and may therefore form a low-mass, low-Z group. The majority of Dwarf Cepheids are in the immediate post-main-sequence phase of evolution. 4 figs. 3 tables, 18 refs
