Infrared excesses of barium stars

2008
A sample of thirty-one barium stars has been studied using JHKLMN photometry. Infrared excesses are found to occur in the H, M, and N bands. The H-excess appears to correlate with the barium intensity (defined by the abnormal strength of the 4554 A BaII line), whereas the excesses in M and N do not.
