The wavelength dependence of polarization in BL Lac objects
Accurate polarization measurements of six BL Lac objects and one highly polarized QSO have been obtained simultaneously at optical and near-infrared wavelengths. The polarizations observed in the infrared are generally ...
The AM Herculis type binary E1405-451
The authors report photometry and polarimetry of the AM Her-type binary E1405-451. For the first time circular polarization has been detected in such an object at wavelengths longer than 1 μm. The light curves and polarization ...
Optical and IR light curves of VV Puppis
Optical (0.36-0.6 micron) light curves with time resolutions of seconds, and infrared (IR) (1.25-2.2 microns) light curves with time resolutions of minutes, are presented for VV Puppis during a high state. The optical light ...
