Iron line diagnostics of the stellar wind in X1908+075
J. Planelles-Villalva, J. M. Torrejón, J. J. Rodes-Roca +1
Aims. X1908+075 is a supergiant X-ray binary (SgXB) composed of an evolved OB star and a neutron star (NS) in a 4.4-day orbit. We aim to characterize the stellar wind, constrain th…
Magnetar field dynamics driven by chiral anomalies without magnetic helicity
Clara Dehman
The chiral magnetic effect (CME), arising from the chiral anomaly and enabling a mutual conversion between magnetic topology and fermionic chirality, is a key mechanism in magnetar…
High-resolution X-ray spectroscopy of Cen X-3 with XMM-Newton
J. J. Rodes-Roca, J. M. Torrejón, G. Sanjurjo-Ferrín +1
The spectral analysis of two XMM-Newton observations of the high-mass X-ray binary system Cen X-3 is presented. In particular, it is focused on the eclipse and out-of-eclipse spect…
Dynamics of magnetoviscous warped discs around compact objects
Arthur G. Suvorov, Kostas Glampedakis
Accretion discs that are tilted with respect to their compact hosts can warp out-of-plane through general relativistic frame-dragging. Warp influences disc dynamics in ways that ha…
Magnetic, thermal and rotational evolution of isolated neutron stars
José A. Pons, Clara Dehman, Daniele Viganò
The strong magnetic fields of neutron stars are closely linked to their observed thermal, spectral, and timing properties, such as the distribution of spin periods and their deriva…
General-relativistic magnetar magnetospheres in 3D with physics-informed neural networks
Petros Stefanou, Arthur G. Suvorov, José A. Pons
Magnetar phenomena are likely intertwined with the location and structure of magnetospheric currents. General-relativistic effects are important in shaping the force-free equilibri…
