TURNER, D. G.; MACLELLAN, R. F.; HENDEN, A. A.  e  BERDNIKOV, L. N.. Space Reddenings For Fifteen Galactic Cepheids. Rev. mex. astron. astrofis [online]. 2011, vol.47, n.2, pp.345-356. ISSN 0185-1101.

Space reddenings are derived for 15 Galactic Cepheids from dereddening CCD BV(RI)c data for AF-type stars in the immediate vicinities of the variables, in conjunction with 2MASS reddenings for BAF-type stars in the same fields. Potential reddening solutions were analyzed using the variable-extinction method to identify stars sharing potentially similar distances and reddenings to the Cepheids, several of which have large color excesses. The intrinsic BV(RI)_c color relation for AF dwarfs was modified slightly in the analysis in order to describe better the colors observed for unreddened stars in the samples.
