Line profile variations in classical Cepheids. Evidence for non-radial pulsations?
V. V. Kovtyukh, S. M. Andrievsky, R. E. Luck +1
We have investigated line profiles in a large sample of Cepheid spectra, and found four stars that show unusual (for Cepheids) line profile structure (bumps or/and asymmetries). Th…
Using Cepheids to determine the galactic abundance gradient I. The solar neighbourhood
S. M. Andrievsky, V. V. Kovtyukh, R. E. Luck +7
A number of studies of abundance gradients in the galactic disk have been performed in recent years. The results obtained are rather disparate: from no detectable gradient to a rat…
Using Cepheids to determine the galactic abundance gradient II. Towards the galactic center
S. M. Andrievsky, D. Bersier, V. V. Kovtyukh +4
Based on spectra obtained at the Anglo-Australian Observatory, we present a discussion of the metallicity of the galactic disc derived using Cepheids at galactocentric distances 4-…
