Blue stragglers - A search for binaries in the infrared
Infrared photometry in the J, H and K bands, performed on a sample of 33 blue stragglers (BS) belonging to 8 open clusters is presented. This photometry has been combined with published Johnson UBV photometry to search for possible cold companions among the BS, as expected for Case B close binary evolution. Probable binaries were identified by
Manteiga, M. et al.
