Unique distant classical Cepheid OGLE GD-CEP-1353 with anomalously high abundances of s- and r-process elements
V. V. Kovtyukh, S. M. Andrievsky, K. Werner +1
While looking for recently discovered distant Cepheids with an interesting chemical composition, we noticed one star (OGLE GD-CEP-1353) with extremely large equivalent widths of sp…
New insights on Ba over-abundance in open clusters. Evidence for the intermediate neutron-capture process at play?
T. Mishenina, M. Pignatari, G. Carraro +6
Recently an increasing number of studies were devoted to measure the abundances of neutron-capture elements heavier than iron in stars belonging to Galactic Open Clusters (OCs). OC…
Accurate luminosities from the oxygen 7771-4 A triplet and the fundamental parameters of F-G supergiants
V. V. Kovtyukh, N. Gorlova, S. I. Belik
The oxygen 7771-4 A triplet is a good indicator of luminosity in A-G supergiants. However, its strength also depends on other atmospheric parameters. In this study, we present the…
