Multicolor polarimetry of stars in the open cluster Trumpler 27

Observations of multicolor polarimetry of the stars in the region of the open cluster Trumpler 27 have been obtained at CASLEO, San Juan, Argentina. These data show rather high values of polarization but with a considerable scatter (P ∼ 4% to 9.5%). On the other hand, the angle of the polarimetric v...
