J/AJ/105/258 J/AJ/105/258 Intracluster dust polarization in Carina nebula H G Marracho E I Vega F J Vrba Astron. J. 105 258 1993 1993AJ....105..258M Extinction Nebulae Photometry, UBVRI Polarization This catalog presents new UBVRI polarimetric observations of 25 stars and BV polarimetric observations of 60 stars which are embedded in the Carina Nebula. Using these data and photometric data from the literature we have modeled and subtracted the foreground dust contribution in the color excess E(B-V) and the visual polarization.
