Title: | Polarization properties of weakly magnetized neutron stars in low-mass X-ray binaries | Authors: | Gnarini, A Ursini, Francesco Matt, G Bianchi, S CAPITANIO, FIAMMA COCCHI, Massimo FARINELLI, Ruben Zhang, W |
Issue Date: | 2022 | Journal: | MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY | Number: | 514 | Issue: | 2 | First Page: | 2561 | Abstract: | X-ray polarimetry missions like Imaging X-ray Polarimetry Explorer will be able to measure for the first time the polarization properties of accreting, weakly magnetized neutron stars in low-mass X-ray binaries. In this work, we present simulations of the expected X-ray polarized signal, including the coronal emission for different geometries of the corona itself, i.e. a slab above the accretion disc and a spherical shell around the neutron star. The simulations are performed with the fully relativistic Monte Carlo code MONK capable of computing the X-ray polarization degree and angle for various physical input parameters of the neutron star, disc, and corona. Different coronal geometries result in significantly different X-ray polarization properties, which can therefore be used to constrain the geometry of the systems. | URI: | http://hdl.handle.net/20.500.12386/34514 | URL: | https://academic.oup.com/mnras/article/514/2/2561/6598828 http://arxiv.org/abs/2206.00749v1 |
