Infrared and optical polarimetry of AM Herculis
Circular polarization observations of AM Herculis have been obtained at wavelengths from 0.55 micron (V) to 2.2 micron (K) using a simultaneous three-channel polarimeter. Polarizations of up to 20 per cent were observed ...
Imaging and polarimetry of the galactic-center in the near infrared
IR images of the Galactic center in H, K, L-prime and M are the bases of the present measurements of positions, magnitudes and colors for 35 sources which can be divided into two classes: those with colors typical of ...
