Parameter constrain in neutron star by twin kHz QPOs
Abstract
We use data on twin kHz QPOs and measured neutron star (NS) masses to test the relation between the lower (ν1) and upper (ν2) peak frequencies predicted with the MHD Alfvén wave oscillation model (AWOM) and the general relativistic precession model (GRPM). In the context of AWOM, the NS radius can be constrained from kHz QPO data and a measured NS mass.
