Abstract
ABSTRACT The projected apparent rotational velocities of the dwarf Cepheids are v sin i ≤ 20 km s-1 for the variables for which spectrograms have been secured at dispersions ≤20 Å mm-1. The rotational velocities are very small compared with the typical rotational velocity of δ Scuti variables. The dwarf Cepheids are also restricted to a much more confined region in the H-R diagram than the δ Scuti variables. Unlike many typical δ Scuti variables, no dwarf Cepheids are found near the ZAMS.
