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.
