Double-hump spectrum, pulse profile dip, and pulsed fraction spectra from the low-accretion regime in the X-ray pulsar MAXI J0655-013

C. Malacaria, S. N. Pike, A. D'Aì +18

Accreting X-ray pulsars (XRPs) undergo different physical regimes depending on the mass accretion rate. Recent observations have shown a dramatic change in the emission properties…

First look at Vela X-1 with XRISM: A simultaneous campaign with XMM-Newton and NuSTAR

C. M. Diez, S. Dupourqué, M. Zhou +6

High-Mass X-ray Binaries (HMXBs) serve as useful laboratories for exploring the behaviour of accreted matter onto compact objects and for probing the complex wind environments of m…

Variable structures in the stellar wind of the HMXB Vela X-1

L. Abalo, P. Kretschmar, F. Fürst +9

Strong stellar winds are an important feature in wind-accreting high-mass X-ray binary (HMXB) systems, providing insights into stellar evolution and their impact on surrounding env…

VLA monitoring of LS V +44 17 reveals scatter in the X-ray--radio correlation of Be/X-ray binaries

J. van den Eijnden, A. Rouco Escorial, J. Alfonso-Garzón +8

LS V +44 17 is a persistent Be/X-ray binary (BeXRB) that displayed a bright, double-peaked period of X-ray activity in late 2022/early 2023. We present a radio monitoring campaign…

The first mm detection of a neutron star high-mass X-ray binary

J. van den Eijnden, L. Sidoli, M. Diaz Trigo +9

Neutron stars accreting from OB supergiants are often divided between persistently and transiently accreting systems, called Supergiant X-ray Binaries (SgXBs) and Supergiant Fast X…

Continuum, cyclotron line, and absorption variability in the high-mass X-ray binary Vela X-1

C. M. Diez, V. Grinberg, F. Fürst +7

Because of its complex clumpy wind, prominent cyclotron resonant scattering features, intrinsic variability and convenient physical parameters (close distance, high inclination, sm…

X-ray emission from magnetized neutron star atmospheres at low mass accretion rates. I. Phase-averaged spectrum

E. Sokolova-Lapa, M. Gornostaev, J. Wilms +12

Recent observations of X-ray pulsars at low luminosities allow, for the first time, to compare theoretical models for the emission from highly magnetized neutron star atmospheres a…

High resolution X-ray spectroscopy of Supergiant HMXB 4U170037 during the compact object eclipse

M. Martínez-Chicharro, V. Grinberg, J. M. Torrejón +6

We present an analysis of the first observation of the iconic High Mass X-ray Binary \so with the \chandra High Energy Transmission Gratings during an X-ray eclipse. The goal of th…

Evidence of Compton cooling during an X-ray flare supports a neutron star nature of the compact object in 4U1700-37

M. Martinez-Chicharro, J. M. Torrejón, L. Oskinova +5

Based on new Chandra X-ray telescope data, we present empirical evidence of plasma Compton cooling during a flare in the non pulsating massive X-ray binary 4U1700-37. This behaviou…

A Suzaku View of Cyclotron Line Sources and Candidates

K. Pottschmidt, S. Suchy, E. Rivers +20

Seventeen accreting neutron star pulsars, mostly high mass X-ray binaries with half of them Be-type transients, are known to exhibit Cyclotron Resonance Scattering Features (CRSFs)…
