J/AJ/130/1880    Cepheids with periods between 3 and 6 days  (Andrievsky+, 2005)

Phase-dependent variation of the fundamental parameters of cepheids. III. Periods between 3 and 6 days. Andrievsky S.M., Luck R.E., Kovtyukh V.V. <Astron. J., 130, 1880-1889 (2005)> =2005AJ....130.1880A
ADC_Keywords: Abundances ; Stars, variable Keywords: Cepheids - stars: abundances - stars: variables: other Abstract: We present the results of a detailed multiphase spectroscopic analysis of six classical Cepheids with pulsation periods between 3 and 6 days. For each star we have derived phased values of effective temperature, surface gravity, microturbulent velocity, and elemental abundances. We show that the elemental abundance results for these Cepheids are consistent for all pulsational phases. Description: Multiphase observations of the program Cepheids were carried out at McDonald Observatory using the Struve 2.1m reflector and the Sandiford echelle spectrograph.
