Scientific paper

Statistical and secular parallaxes combined with an analysis of individual absolute magnitudes indicate that the classical barium stars have a mean absolute visual mgnitude of 1.4 with an intrinsic dispersion of 1.3 (under the standard assumption that the absolute magnitude distribution can be modeled as a Gaussian). These values suggest that, although the majority of barium stars are normal giants, a large fraction are subgiants and bright giants or supergiants. A comparison with the results of other statistical studies shows that a systematic effect is still present in the data set that causes measured mean absolute magnitude to increase with apparent magnitude. The effect appears to be tied to the observation that barium-weak stars are underrepresented at faint apparent magnitudes.
