| Abstract: |
The Population I monoperiodic short-period Cepheids have been divided into two groups, C-a and C-b stars, on the basis of the Fourier parameters of their light curves. Their observed properties and evidence for double-mode Cepheids are considered, and it is concluded that C-b stars are firt-overtone mode pulsators whereas C-a stars are fundamental mode pulsators. |
