Phosphorus in cool stars of various metallicities: The non-local thermodynamic equilibrium consideration
S. M. Andrievsky, S. A. Korotin
The phosphorus abundance distribution in field stars as a function of metallicity reveals a complex pattern. The LTE data for [P/Fe] in the low-metallicity range are sparse and sca…
Lithium Cepheid V708 Car with an unusual chemical composition
V. V. Kovtyukh, S. M. Andrievsky, K. Werner +2
The purpose of this work is to spectroscopically analyse the classical Cepheid V708 Car. A preliminary check of the spectrum of V708 Car showed that this is a lithium-rich supergia…
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…
Abundance of radioactive technetium in Przybylski's star revisited
S. M. Andrievsky, S. A. Korotin, K. Werner
We have searched for lines of the radioactive element technetium (Tc) in the spectrum of Przybylski's star (HD101065). The nuclei of this chemical element are formed in the slow pr…
An enigma of Przybylski's star: is there promethium on its surface?
Sergei M. Andrievsky, Sergey A. Korotin, Klaus Werner +1
We carried out a new attempt to check for the presence promethium lines in the spectrum of HD101065 (Przybylski's star). The neutron capture element promethium does not have stable…
Probing the Przybylski star for Deuterium
Sergei M. Andrievsky, Valery V. Kovtyukh
The Przybylski star spectrum has been studied in order to search for deuterium lines. Since this star is extremely enriched in the s-process elements, which are the product of inte…
