Abstract:
We present the first optical polarimetric study of the two
transitional pulsars PSR J1023+0038 and XSS J12270-4859. This work is
focused on the search for intrinsically linearly polarised optical
emission from the two systems. To this aim, we carried out multiband
optical (BVRi) and near-infrared (JHK) photo-polarimetric
observations of the two systems using the ESO New Technology Telescope
(NTT) at La Silla (Chile), equipped with the EFOSC2 and the SOFI
instruments.
Description:
The systems PSR J1023+0038 and XSS J12270-4859 were observed in
quiescence on 8 and 9 February 2015 (respectively) with the ESO New
Technology Telescope (NTT) located at La Silla (Chile), equipped with
the EFOSC2 camera in polarimetric mode, using the B, V, R, i filters.
