An Investigation of Luminous X-Ray Pulsars: Exploring Accretion Onto the Magnetized Neutron Star LMC X-4
Abstract
X-ray pulsars are neutron stars in which magnetic forces dominate accretion within the magnetosphere. These systems offer unique laboratories to study magnetic accretion and the behavior of matter under extreme densities, magnetic fields, and gravitational forces. Using joint observations with NuSTAR and XMM-Newton, we observe the complete precession of the warped accretion disk around the X-ray pulsar LMC X-4, and measure the relative phase between the pulsar beam and the softer X-ray photons reprocessed by the disk. This allows us to perform tomography to explore the inner magnetized accretion flow. Additionally, we investigate the unusual flaring events observed from LMC X-4 during October and November of 2015.
