A differential curve-of-growth analysis of the candidate barium star 93 Her.
Abstract
A differential curve- of-growth analysis of 93 Herculis relative to e Virginis shows that the star is generally metal deficient, [Fe/H] = - 0.3, but barium and other heavy elements are slightly enhanced, [Ba/Fe] = +0.5.
