barium star
(Ba star)
(star showing unexpected barium lines)
A barium star is a star with atypical barium spectral lines,
typically a G-type star or K-type star. They show signs of elements
that would be synthesized later in their life (if at all).
They are thought to be the result of binary-star interaction,
i.e., mass transfer from a companion in its asymptotic giant branch (AGB) phase.
