J/PAZh/43/407 S5 0716+714 polarization & brightness 1991-2004 (Doroshenko+ 2017)

Polarization and brightness of the blazar S5 0716+714 in 1991-2004. Doroshenko V.T., Kiselev N.N. <Pis'ma Astron. Zh. 43, 407 (2017)> =2017PAZh...43..407D (SIMBAD/NED BibCode) =2017AstL...43..356D
ADC_Keywords: BL Lac objects ; Photometry, UBVRI ; Polarization Keywords: active galactic nuclei - BL Lac objects - individual object: S5 0716+714 - photometry - polarimetry Abstract: We investigate the photometric and polarimetric behavior of the blazar S5 0716+714 based on the observations carried out in 1991-2004 at the 125-cm Crimean Astrophysical Observatory telescope (AZT11) with a photopolarimeter that allows simultaneous polarization and brightness measurements to be made in the UBV RI bands. We also provide the UBV photometry for the blazar obtained in 2000-2009 with a 60-cm telescope at the Crimean Station of the Sternberg Astronomical Institute. The pattern of flux variability and the correlation between the brightness, color, and polarization variations have been investigated. In this time interval the blazar showed a significant brightness and polarization variability similar to noise processes. Description: The brightness and polarization measurements for S5 0716+714 were made with a double-beam five channel photometer-polarimeter designed and constructed by V. Piirola. The instrument is mounted at the Cassegrain focus (f/12.8) of the 125-cm CrAO telescope (AZT11). Apart from the AZT11 data, we used the observations of S5 0716+714 carried out by V.T. Doroshenko in 2000-2009 with the 60-cm telescope at the Southern Station of the Sternberg Astronomical Institute with a single-channel photon-counting photometer in a UBV system close to the Johnson standard system.
