This paper presents the large-scale polarized sky as seen by Planck HFI at 353 GHz, which is the most sensitive Planck channel for dust polarization.  ...  There is a systematic decrease in the dust polarization fraction with increasing dust column density, and we interpret the features of this correlation in light of both radiative grain alignment predictions  ...  Such a decrease of the polarization fraction toward large column densities on small (∼a few 0.1 pc) scales was reported previously in ground-based measurements of polarization both in emission (Ward-Thompson  ...

The DC white dwarf in SDSS0303+0054 has a mass of Mwd>0.85Msun, making it unusually massive for a post-common envelope system.  ...  A spectral decomposition/fitting technique was then employed to determine the white dwarf effective temperatures and surface gravities, as well as the spectral types of the companion stars.  ...  For the uniform illumination case, R = (4/3π)R sec , there were no solutions for K sec = K sec, Hα , but a few solutions for the K sec = K sec, Ca II .  ...
