Linear polarization of T-Tauri stars
(1981)
Linear polarization observations over the wavelength range 0.44-2.2 microns are presented for six T Tauri type stars. All of the stars studied show substantial polarization in the infrared, while T Tau itself (and probably ...
Infrared and optical polarization of Markarian-421
(1981)
Observations of the polarization of Mrk 421 in the V, J, and K bands are presented. The infrared radiation shows variable polarization with a range of at least 2-4%. The spectrum of the nonthermal source in the VJK regions ...
