Interpretation of the variable linear polarization of X-ray transient AO 538-66

The optical linear polarization from the X-ray transient AO 538-66 is discussed. Assuming this system is a neutron star binary and the polarization is produced by Thomson scattering in the envelope of the Be star companion, it is shown that the features of the polarization variability can be explain...

Zusammenfassung:	The optical linear polarization from the X-ray transient AO 538-66 is discussed. Assuming this system is a neutron star binary and the polarization is produced by Thomson scattering in the envelope of the Be star companion, it is shown that the features of the polarization variability can be explained by a model in which the neutron star moves in a highly eccentric orbit (e greater than 0.4) around its more massive companion.
