II/192              UBV Photometry of Barium Stars    (Watanabe+ 1993)

UBV Photometry of Barium Stars

Description:
    Magnitudes in V and B-V and U-B colors observed by the 91-cm telescope
    at Okayama  are presented for  109 stars including  both classical and
    marginal barium  stars. The two-color  diagram shows a  fair amount of
    spread. This can be interpreted by interstellar reddening and variable
    amounts  of line blocking  effect. Both classical  and marginal barium
    stars form a fairly homogeneous group.
