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.
