| Abstract: | The Population II Cepheid pulsational variables AL Vir (P = 10.3 days) and W Vir (P = 17.3 days) were observed with IUE at two phases each. Only low-dispersion mid-UV exposures were feasible, but were sufficient to show a great range in Mg II emission behavior. The relationship to phase variation of emission in classical (Pop I) Cepheids of long period is unclear. |
