Spectral Analysis of the Egress and Ingress Phases of Cen X-3 with XRISM/Resolve

J. Planelles-Villalva, L. Gu, J. J. Rodes-Roca +7

We investigate the phase-resolved X-ray spectral evolution of the high-mass X-ray binary Cen X-3 across eclipse ingress and egress, using two out-of-eclipse intervals as references…

Spin-down of the accreting magnetar candidate 4U 0114+65: possible first evidence for a strong coupling regime

Graciela Sanjurjo-Ferrín, Jose Miguel Torrejón, Konstantin Postnov +3

4U~0114+65 is a high-mass X-ray binary composed of the B1\,Ia supergiant V*~V662~Cas and one of the slowest known accreting neutron stars, with a spin period of 9.4 ks. In 20…

Blind Line Search System: BLiSS

Luis Abalo, Graciela Sanjurjo-Ferrín, Jessica Planelles-Villalva +2

The increasing sensitivity and spectral resolution of current and forthcoming X-ray observatories, including \textit{XRISM} and \textit{NewAthena}, are expected to reveal increasin…

Spectroscopic modeling of ionic structure in stellar winds of high-mass X-ray binaries

G. Sanjurjo-Ferrín, V. Grinberg, I. El Mellah +6

High-mass X-ray binaries (HMXBs) provide a natural laboratory to study radiatively driven stellar winds under strong external X-ray irradiation. As the compact object moves along i…

A thousand looks at X Persei: X-ray spectroscopy at high time resolution

G. Sanjurjo-Ferrín, J. M. Torrejón, J. J. Rodes-Roca +3

X Persei is a classical Be/X-ray binary composed of an O9.5III-B0V Be-type star and a neutron star (NS). The NS exhibits coherent pulsations with a spin period of ~837 s, orbiting…

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…
