Scientific paper

The results of J, H, K photometry on 41 RS CVn systems and data on 40 RS CVn systems identified with IRAS point sources are given. For those systems in which the components have individual spectral types, the infrared color excess is discussed. It is found that only very few systems show infrared excesses. (UX Ari, Z Her and HR 1099 in the near infrared, and SZ Psz at 12 microns). For systems having fluxes at 12 and 25 microns and K magnitudes, a color-color diagram is plotted, and the majority of points is found to be lying close to the black body line. These observations are in conflict with the statement that infrared excess is a general characteristic of RS CVn systems.
