Barium abundances in cool dwarf stars as a constraint to s- and r-process nucleosynthesis

Mashonkina L.; Gehren T.; Bikmaev I. (1999)

We revise barium abundances in 11 cool stars with metallicities ranging from -2.65 to 0.05. The results are based on differential NLTE model atmosphere analyses of spectra that have a typical S/N of 200 and a resolution ...
Barium and europium abundances in cool dwarf stars and nucleosynthesis of heavy elements

Mashonkina L.; Gehren T. (2000)

We revise barium abundances in 29 cool stars with metallicities [Fe/H] ranging from -2.20 to 0.07 and europium abundances in 15 stars with [Fe/H] from -1.52 to 0.07. The sample has been extracted from Fuhrmann's lists ...
Heavy element abundances in cool dwarf stars: An implication for the evolution of the Galaxy

Mashonkina L.; Gehren T. (2001)

We present revised strontium, barium and europium abundances for 63 cool stars with metallicities [Fe/H] ranging from -2.20 to 0.25. The stellar sample has been extracted from Fuhrmann's lists (1998, 2001). It is confined ...
Mg, Ba and Eu abundances in thick disk and halo stars

Mashonkina L.; Gehren T.; Travaglio C.; Borkova T. (2003)

Our sample of cool dwarf stars from previous papers (Mashonkina & Gehren 2000, 2001) is extended in this study including 15 moderately metal-deficient stars. The samples of halo and thick disk stars have overlapping ...
