Abstract
We present preliminary results obtained from optical (B, V, R, and I) linear polarimetric observations of the O+O massive binary DH Cep. The observations were made on six nights in 2017 with the Aries IMaging POLarimeter (AIMPOL) mounted at the back of the 1.04-m Sampurnanand Telescope of ARIES. The average intrinsic linear polarization in each of the B, V, R, and I photometric bands is found to be less than 1%. The degree of polarization as well as the polarization angle appear to be orbital phase dependent. The significant polarization variability noticed towards shorter wavelengths (i.e. B and V bands) is indicative of the asymmetric circumstellar envelope.
